+## Backup and restore
+All data and [configuration](Shaarli-configuration.md) is kept in the `data` directory. Backup this directory: 
+```bash
+rsync -avzP my.server.com:/var/www/shaarli.mydomain.org/data ~/backups/shaarli-data-$(date +%Y-%m-%d_%H%M)
+```
+It is strongly recommended to do periodic, automatic backups to a seperate machine. You can automate the command above using a cron job or full-featured backup solutions such as [rsnapshot](https://rsnapshot.org/)
+To restore a backup, simply put back the `data/` directory in place, owerwriting any existing files.

-## Plain text search
-Use the `Search text` field to search in _any_ of the fields of all links (Title, URL, Description...)
-**Exclude text/tags:** Use the `-` operator before a word or tag (example `-uninteresting`) to prevent entries containing (or tagged) `uninteresting` from showing up in the search results.
-**Exact text search:** Use double-quotes (example `"exact search"`) to search for the exact expression.
-Both exclude patterns and exact searches can be combined with normal searches (example `"exact search" term otherterm -notthis "very exact" stuff -notagain`)
-## Tags search
-Use the `Filter by tags` field to restrict displayed links to entries tagged with one or multiple tags (use space to separate tags).  
-**Hidden tags:** Tags starting with a dot `.` (example `.secret`) are private. They can only be seen and searched when logged in.
-### Tag cloud
-The `Tag cloud` page diplays a "cloud" view of all tags in your Shaarli.
- * The most frequently used tags are displayed with a bigger font size.
- * When sorting by `Most used` or `Alphabetical`, tags are displayed as a _list_, along with counters and edit/delete buttons for each tag.
- * Clicking on any tag will display a list of all Shaares matching this tag.
- * Clicking on the counter next to a tag `example`, will filter the tag cloud to only display tags found in Shaares tagged `example`. Repeat this any number of times to further filter the tag cloud. Click `List all links with those tags` to display Shaares matching your current tag filter.
-## Filtering RSS feeds/Picture wall
-RSS feeds can also be restricted to only return items matching a text/tag search: see [RSS feeds](RSS-feeds).
-## Filter buttons
-Filter buttons can be found at the top left of the link list. They allow you to apply different filters to the list:
- * **Private links:** When this toggle button is enabled, only shaares set to `private` will be shown.
- * **Untagged links:** When the this toggle button is enabled (top left of the link list), only shaares _without any tags_ will be shown in the link list.
- 
-Filter buttons are only available when logged in.

-## Local development
-A [`Makefile`](https://github.com/shaarli/Shaarli/blob/master/Makefile) is available to perform project-related operations:
- Documentation - generate a local HTML copy of the GitHub wiki
- [Static analysis](Static-analysis) - check that the code is compliant to PHP conventions
- [Unit tests](Unit-tests) - ensure there are no regressions introduced by new commits
-## Automatic builds
-[Travis CI](http://docs.travis-ci.com/) is a Continuous Integration build server, that runs a build:
- each time a commit is merged to the mainline (`master` branch)
- each time a Pull Request is submitted or updated
-A build is composed of several jobs: one for each supported PHP version (see [Server requirements](Server requirements)).
-Each build job:
- updates Composer
- installs 3rd-party test dependencies with Composer
- runs [Unit tests](Unit-tests)
- runs ESLint check
-After all jobs have finished, Travis returns the results to GitHub:
- a status icon represents the result for the `master` branch: [![](https://api.travis-ci.org/shaarli/Shaarli.svg)](https://travis-ci.org/shaarli/Shaarli)
- Pull Requests are updated with the Travis result
-    - Green: all tests have passed
-    - Red: some tests failed
-    - Orange: tests are pending
-## Documentation
-[mkdocs](https://www.mkdocs.org/) is used to convert markdown documentation to HTML pages. The [public documentation](https://shaarli.readthedocs.io/en/master/) website is rendered and hosted by [readthedocs.org](https://readthedocs.org/). A copy of the documentation is also included in prebuilt [release archives](https://github.com/shaarli/Shaarli/releases) (`doc/html/` path in your Shaarli installation). To generate the HTML documentation locally, install a recent version of Python `setuptools` and run    `make doc`.

+# Docker
+[Docker](https://docs.docker.com/get-started/overview/) is an open platform for developing, shipping, and running applications
+## Install Docker
+Install [Docker](https://docs.docker.com/engine/install/), by following the instructions relevant to your OS / distribution, and start the service. For example on [Debian](https://docs.docker.com/engine/install/debian/):
+```bash
+# update your package lists
+sudo apt update
+# remove old versions
+sudo apt-get remove docker docker-engine docker.io containerd runc
+# install requirements
+sudo apt-get install apt-transport-https ca-certificates curl gnupg-agent software-properties-common
+# add docker's GPG signing key
+curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add -
+# add the repository
+sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/debian $(lsb_release -cs) stable"
+# install docker engine
+sudo apt-get update
+sudo apt-get install docker-ce docker-ce-cli containerd.io
+# Start and enable Docker service
+sudo systemctl enable docker && sudo systemctl start docker
+# verify that Docker is properly configured
+sudo docker run hello-world
+```
+In order to run Docker commands as a non-root user, you must add the `docker` group to this user:
+```bash
+# Add docker group as secondary group
+sudo usermod -aG docker your-user
+# Reboot or logout
+# Then verify that Docker is properly configured, as "your-user"
+docker run hello-world
+```
+## Get and run a Shaarli image
+Shaarli images are available on [DockerHub](https://hub.docker.com/r/shaarli/shaarli/) `shaarli/shaarli`:
+- `latest`: latest branch (last release)
+- `stable`: stable branch (last release in previous major version)
+- `master`: master branch (development branch)
+These images are built automatically on DockerHub and rely on:
+- [Alpine Linux](https://www.alpinelinux.org/)
+- [PHP7-FPM](http://php-fpm.org/)
+- [Nginx](http://nginx.org/)
+Additional Dockerfiles are provided for the `arm32v7` platform, relying on [Linuxserver.io Alpine armhf images](https://hub.docker.com/r/lsiobase/alpine.armhf/). These images must be built using [`docker build`](https://docs.docker.com/engine/reference/commandline/build/) on an `arm32v7` machine or using an emulator such as [qemu](https://resin.io/blog/building-arm-containers-on-any-x86-machine-even-dockerhub/).
+Here is an example of how to run Shaarli latest image using Docker:
+```bash
+# download the 'latest' image from dockerhub
+docker pull shaarli/shaarli
+# create persistent data volumes/directories on the host
+docker volume create shaarli-data

+```
+After running `docker run` command, your Shaarli instance should be available on the host machine at [localhost:8000](http://localhost:8000). In order to access your instance through a reverse proxy, we recommend using our [Docker Compose](#docker-compose) build.
+## Docker Compose
+A [Compose file](https://docs.docker.com/compose/compose-file/) is a common format for defining and running multi-container Docker applications.
+A `docker-compose.yml` file can be used to run a persistent/autostarted shaarli service using [Docker Compose](https://docs.docker.com/compose/) or in a [Docker stack](https://docs.docker.com/engine/reference/commandline/stack_deploy/).
+Shaarli provides configuration file for Docker Compose, that will setup a Shaarli instance, a [Træfik](https://containo.us/traefik/) instance (reverse proxy) with [Let's Encrypt](https://letsencrypt.org/) certificates, a Docker network, and volumes for Shaarli data and Træfik TLS configuration and certificates.
+Download docker-compose from the [release page](https://docs.docker.com/compose/install/):
+```bash
+$ sudo curl -L "https://github.com/docker/compose/releases/download/1.26.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
+$ sudo chmod +x /usr/local/bin/docker-compose
+```
+To run Shaarli container and its reverse proxy, you can execute the following commands:
+```bash
+# create a new directory to store the configuration:
+$ mkdir shaarli && cd shaarli
+# Download the latest version of Shaarli's docker-compose.yml
+$ curl -L https://raw.githubusercontent.com/shaarli/Shaarli/latest/docker-compose.yml -o docker-compose.yml
+# Create the .env file and fill in your VPS and domain information
+# (replace <MY_SHAARLI_DOMAIN> and <MY_CONTACT_EMAIL> with your actual information)
+$ echo 'SHAARLI_VIRTUAL_HOST=shaarli.mydomain.org' > .env
+$ echo 'SHAARLI_LETSENCRYPT_EMAIL=admin@mydomain.org' >> .env
+# Pull the Docker images
+$ docker-compose pull
+# Run!
+$ docker-compose up -d
+```
+After a few seconds, you should be able to access your Shaarli instance at [https://shaarli.mydomain.org](https://shaarli.mydomain.org) (replace your own domain name).
+## Running dockerized Shaarli as a systemd service
+It is possible to start a dockerized Shaarli instance as a systemd service (systemd is the service management tool on several distributions). After installing Docker, use the following steps to run your shaarli container Shaarli to run on system start.
+As root, create `/etc/systemd/system/docker.shaarli.service`:
+```ini
+[Unit]
+Description=Shaarli Bookmark Manager Container
+After=docker.service
+Requires=docker.service
+[Service]
+Restart=always
+# Put any environment you want in an included file, like $host- or $domainname in this example
+EnvironmentFile=/etc/sysconfig/box-environment
+# It's just an example..
+ExecStart=/usr/bin/docker run \
+  -p 28010:80 \
+  --name ${hostname}-shaarli \
+  --hostname shaarli.${domainname} \
+  -v /srv/docker-volumes-local/shaarli-data:/var/www/shaarli/data:rw \
+  -v /etc/localtime:/etc/localtime:ro \
+  shaarli/shaarli:latest
+ExecStop=/usr/bin/docker rm -f ${hostname}-shaarli
+[Install]
+WantedBy=multi-user.target
+```
+```bash
+# reload systemd services definitions
+systemctl daemon-reload
+# start the servie and enable it a boot time
+systemctl enable docker.shaarli.service --now
+# verify that the service is running
+systemctl status docker.*
+# inspect system log if needed
+journalctl -f
+```
+## Docker cheatsheet
+```bash
+# pull/update an image
+$ docker pull shaarli/shaarli:release
+# run a container from an image
+$ docker run shaarli/shaarli:latest
+# list available images
+$ docker images ls
+# list running containers
+$ docker ps
+# list running AND stopped containers
+$ docker ps -a
+# run a command in a running container
+$ docker exec -ti <container-name-or-first-letters-of-id> bash
+# follow logs of a running container
+$ docker logs -f <container-name-or-first-letters-of-id>
+# delete unused images to free up disk space
+$ docker system prune --images
+# delete unused volumes to free up disk space (CAUTION all data in unused volumes will be lost)
+$ docker system prunt --volumes
+# delete unused containers
+$ docker system prune
+```

-### Why did you create Shaarli ?
-I was a StumbleUpon user. Then I got fed up with they big toolbar. I switched to delicious, which was lighter, faster and more beautiful. Until Yahoo bought it. Then the export API broke all the time, delicious became slow and was ditched by Yahoo. I switched to Diigo, which is not bad, but does too much. And Diigo is sslllooooowww and their Firefox extension a bit buggy. And… oh… **their Firefox addon sends to Diigo every single URL you visit** (Don't believe me ? Use [Tamper Data](https://addons.mozilla.org/en-US/firefox/addon/tamper-data/) and open any page).
-Enough is enough. Saving simple links should not be a complicated heavy thing. I ditched them all and wrote my own: Shaarli. It's simple, but it does the job and does it well. And my data is not hosted on a foreign server, but on my server.
-### Why use Shaarli and not Delicious/Diigo ?
-With Shaarli:
- The data is yours: It's hosted on your server.
- Never fear of having your data locked-in.
- Never fear to have your data sold to third party.
- Your private links are not hosted on a third party server.
- You are not tracked by browser addons (like Diigo does)
- You can change the look and feel of the pages if you want.
- You can change the behaviour of the program.
- It's magnitude faster than most bookmarking services.
-### What does Shaarli mean?
-Shaarli stands for _shaaring_ your _links_.
-### My Shaarli is broken!
-First of all, ensure that both the [web server](Server-configuration) and
-[Shaarli](Shaarli-configuration) are correctly configured, and that your
-installation is [supported](Server-configuration).
-If everything looks right but the issue(s) remain(s), please:
- take a look at the [troubleshooting](Troubleshooting) section
- come [chat with us](https://gitter.im/shaarli/Shaarli) on Gitter, we'll be happy to help ;-)
- browse active [issues](https://github.com/shaarli/Shaarli/issues) and [Pull Requests](https://github.com/shaarli/Shaarli/pulls)
-    - if you find one that is related to the issue, feel free to comment and provide additional details (host/Shaarli setup)
-    - else, [open a new issue](https://github.com/shaarli/Shaarli/issues/new), and provide information about the problem:
-        - _what happens?_ - display glitches, invalid data, security flaws...
-        - _what is your configuration?_  - OS, server version, activated extensions, web browser...
-        - _is it reproducible?_
-### Why not use a real database? Files are slow!
-Does browsing [this page](http://sebsauvage.net/links/) feel slow? Try browsing older pages, too.
-It's not slow at all, is it? And don't forget the database contains more than 16000 links, and it's on a shared host, with 32000 visitors/day for my website alone. And it's still damn fast. Why?
-The data file is only 3.7 Mb. It's read 99% of the time, and is probably already in the operation system disk cache. So generating a page involves no I/O at all most of the time.

-The host where the API client is invoked should also be synchronized with NTP,
-see [token expiration](#payload).
-## Authentication
-All requests to Shaarli's API must include a JWT token to verify their authenticity.
-This token has to be included as an HTTP header called `Authentication: Bearer <jwt token>`.
-JWT resources :
- [jwt.io](https://jwt.io) (including a list of client per language).
- RFC : https://tools.ietf.org/html/rfc7519
- https://float-middle.com/json-web-tokens-jwt-vs-sessions/
- HackerNews thread: https://news.ycombinator.com/item?id=11929267
-### Shaarli JWT Token
-JWT tokens are composed by three parts, separated by a dot `.` and encoded in base64:
-```
-[header].[payload].[signature]
-```
-#### Header
-Shaarli only allow one hash algorithm, so the header will always be the same:
-```json
-{
-    "typ": "JWT",
-    "alg": "HS512"
-}
-```
-Encoded in base64, it gives:
-```
-ewogICAgICAgICJ0eXAiOiAiSldUIiwKICAgICAgICAiYWxnIjogIkhTNTEyIgogICAgfQ==
-```
-#### Payload
-**Token expiration**
-To avoid infinite token validity, JWT tokens must include their creation date
-in UNIX timestamp format (timezone independent - UTC) under the key `iat` (issued at).
-This token will be valid during **9 minutes**.
-```json
-{
-    "iat": 1468663519
-}
-```
-See [RFC reference](https://tools.ietf.org/html/rfc7519#section-4.1.6).
-#### Signature
+The host where the API client is invoked should also be synchronized with NTP, see _payload/token expiration_
-The signature authenticate the token validity. It contains the base64 of the header and the body, separated by a dot `.`, hashed in SHA512 with the API secret available in Shaarli administration page.
-Signature example with PHP:
-```php
-$content = base64_encode($header) . '.' . base64_encode($payload);
-$signature = hash_hmac('sha512', $content, $secret);
-```

+## Implementation
+### Authentication
+- All requests to Shaarli's API must include a **JWT token** to verify their authenticity.
+- This token must be included as an HTTP header called `Authentication: Bearer <jwt token>`.
+- JWT tokens are composed by three parts, separated by a dot `.` and encoded in base64:
+```
+[header].[payload].[signature]
+```
+##### Header
+Shaarli only allow one hash algorithm, so the header will always be the same:
+```json
+{
+    "typ": "JWT",
+    "alg": "HS512"
+}
+```
+Encoded in base64, it gives:

+```
+##### Payload
+Token expiration: To avoid infinite token validity, JWT tokens must include their creation date in UNIX timestamp format (timezone independent - UTC) under the key `iat` (issued at) field ([1](https://tools.ietf.org/html/rfc7519#section-4.1.6)). This token will be valid during **9 minutes**.
+```json
+{
+    "iat": 1468663519
+}
+```
+##### Signature
+The signature authenticates the token validity. It contains the base64 of the header and the body, separated by a dot `.`, hashed in SHA512 with the API secret available in Shaarli administration page.
+Example signature with PHP:
+```php
+$content = base64_encode($header) . '.' . base64_encode($payload);
+$signature = hash_hmac('sha512', $content, $secret);

-### Feeds options
-Feeds are available in ATOM with `/feed/atom` and RSS with `/feed/rss`.
-Options:
- You can use `permalinks` in the feed URL to get permalink to Shaares instead of direct link to shaared URL.
-    - E.G. `https://my.shaarli.domain/feed/atom?permalinks`.
- You can use `nb` parameter in the feed URL to specify the number of Shaares you want in a feed (default if not specified: `50`). The keyword `all` is available if you want everything.
-    - `https://my.shaarli.domain/feed/atom?permalinks&nb=42`
-    - `https://my.shaarli.domain/feed/atom?permalinks&nb=all`
-### RSS Feeds or Picture Wall for a specific search/tag
-It is possible to filter RSS/ATOM feeds and Picture Wall on a Shaarli to **only display results of a specific search, or for a specific tag**.
-For example, if you want to subscribe only to links tagged `photography`:
- Go to the desired Shaarli instance.
- Search for the `photography` tag in the _Filter by tag_ box. Links tagged `photography` are displayed.
- Click on the `RSS Feed` button.
- You are presented with an RSS feed showing only these links. Subscribe to it to receive only updates with this tag.
- The same method **also works for a full-text search** (_Search_ box) **and for the Picture Wall** (want to only see pictures about `nature`?)
- You can also build the URLs manually:
-    - `https://my.shaarli.domain/?do=rss&searchtags=nature`
-    - `https://my.shaarli.domain/links/picture-wall?searchterm=poney`

-See  [Git - Maintaining a project - Tagging your 
-releases](http://git-scm.com/book/en/v2/Distributed-Git-Maintaining-a-Project#Tagging-Your-Releases).
-## Prerequisites
-This guide assumes that you have:
- a GPG key matching your GitHub authentication credentials
-    - i.e., the email address identified by the GPG key is the same as the one in your `~/.gitconfig` 
- a GitHub fork of Shaarli
- a local clone of your Shaarli fork, with the following remotes:
-    - `origin` pointing to your GitHub fork
-    - `upstream` pointing to the main Shaarli repository
- maintainer permissions on the main Shaarli repository, to:
-    - push the signed tag
-    - create a new release
- [Composer](https://getcomposer.org/) needs to be installed
- The [venv](https://docs.python.org/3/library/venv.html) Python 3 module needs to be installed for HTML documentation generation.
-## GitHub release draft and `CHANGELOG.md`
-See http://keepachangelog.com/en/0.3.0/ for changelog formatting.
-### GitHub release draft
-GitHub allows drafting the release note for the upcoming release, from the [Releases](https://github.com/shaarli/Shaarli/releases) page. This way, the release note can be drafted while contributions are merged to `master`.
-### `CHANGELOG.md`
-This file should contain the same information as the release note draft for the upcoming version.
-Update it to:
- add new entries (additions, fixes, etc.)
- mark the current version as released by setting its date and link
- add a new section for the future unreleased version
-```bash
-$ cd /path/to/shaarli
-$ nano CHANGELOG.md
-[...]
-## vA.B.C - UNRELEASED
-TBA
-## [vX.Y.Z](https://github.com/shaarli/Shaarli/releases/tag/vX.Y.Z) - YYYY-MM-DD
-[...]
-```
-## Increment the version code, update docs, create and push a signed tag
-### Update the list of Git contributors
-```bash
-$ make authors
-$ git commit -s -m "Update AUTHORS"
-```
-### Create and merge a Pull Request
-This one is pretty straightforward ;-)
-### Bump Shaarli version to v0.x branch
-```bash
-$ git checkout master
-$ git fetch upstream
-$ git pull upstream master
-# IF the branch doesn't exists
-$ git checkout -b v0.5
-# OR if the branch already exists
-$ git checkout v0.5
-$ git rebase upstream/master
-# Bump shaarli version from dev to 0.5.0, **without the `v`**
-$ vim shaarli_version.php
-$ git add shaarli_version
-$ git commit -s -m "Bump Shaarli version to v0.5.0"
-$ git push upstream v0.5
-```
-### Create and push a signed tag
-```bash
-# update your local copy
-$ git checkout v0.5
-$ git fetch upstream
-$ git pull upstream v0.5
-# create a signed tag
-$ git tag -s -m "Release v0.5.0" v0.5.0
-# push it to "upstream"
-$ git push --tags upstream
-```
-### Verify a signed tag
-[`v0.5.0`](https://github.com/shaarli/Shaarli/releases/tag/v0.5.0) is the first GPG-signed tag pushed on the Community Shaarli.
-Let's have a look at its signature!
-```bash
-$ cd /path/to/shaarli
-$ git fetch upstream
-# get the SHA1 reference of the tag
-$ git show-ref tags/v0.5.0
-f7762cf803f03f5caf4b8078359a63783d0090c1 refs/tags/v0.5.0

-gpg: Good signature from "VirtualTam <virtualtam@flibidi.net>" [ultimate]
-```
-## Publish the GitHub release
-### Update release badges
-Update `README.md` so version badges display and point to the newly released Shaarli version(s), in the `master` branch.
-### Create a GitHub release from a Git tag
-From the previously drafted release:
- edit the release notes (if needed)
- specify the appropriate Git tag
- publish the release
- profit!
-### Generate and upload all-in-one release archives
-Users with a shared hosting may have:
- no SSH access
- no possibility to install PHP packages or server extensions
- no possibility to run scripts
-To ease Shaarli installations, it is possible to generate and upload additional release archives,
-that will contain Shaarli code plus all required third-party libraries.
-**From the `v0.5` branch:**
-```bash
-$ make release_archive
-```
-This will create the following archives:
- `shaarli-vX.Y.Z-full.tar`
- `shaarli-vX.Y.Z-full.zip`
-The archives need to be manually uploaded on the previously created GitHub release.
-### Update `stable` and `latest` branches
-```
-$ git checkout latest
-# latest release
-$ git merge v0.5.0
-# fix eventual conflicts
-$ make test
-$ git push upstream latest
-$ git checkout stable
-# latest previous major
-$ git merge v0.4.5 
-# fix eventual conflicts
-$ make test
-$ git push upstream stable

+# Reverse proxy
+If Shaarli is hosted on a server behind a [reverse proxy](https://en.wikipedia.org/wiki/Reverse_proxy) (i.e. there is a proxy server between clients and the web server hosting Shaarli), configure it accordingly. See [Reverse proxy](Reverse-proxy.md) configuration. In this example:
+- The Shaarli application server exposes port `10080` to the proxy (for example docker container started with `--publish 127.0.0.1:10080:80`).
+- The Shaarli application server runs at `127.0.0.1` (container). Replace with the server's IP address if running on a different machine.
+- Shaarli's Fully Qualified Domain Name (FQDN) is `shaarli.mydomain.org`.
+- No HTTPS is setup on the application server, SSL termination is done at the reverse proxy.
+In your [Shaarli configuration](Shaarli-configuration) `data/config.json.php`, add the public IP of your proxy under `security.trusted_proxies`.
+See also [proxy-related](https://github.com/shaarli/Shaarli/issues?utf8=%E2%9C%93&q=label%3Aproxy+) issues.

-## Client browser
- Shaarli relies on `HTTP_REFERER` for some functions (like redirects and clicking on tags). If you have disabled or masqueraded `HTTP_REFERER` in your browser, some features of Shaarli may not work
-## Server and sessions
- Directories are protected using `.htaccess` files
- Forms are protected against XSRF (Cross-site requests forgery):
-    - Forms which act on data (save,delete…) contain a token generated by the server.
-    - Any posted form which does not contain a valid token is rejected.
-    - Any token can only be used once.
-    - Tokens are attached to the session and cannot be reused in another session.
- Sessions automatically expire after 60 minutes.
- Sessions are protected against hijacking: the session ID cannot be used from a different IP address.
-## Shaarli datastore and configuration
- The password is salted, hashed and stored in the data subdirectory, in a PHP file, and protected by htaccess. Even if the webserver does not support htaccess, the hash is not readable by URL. Even if the .php file is stolen, the password cannot deduced from the hash. The salt prevents rainbow-tables attacks.
- Links are stored as an associative array which is serialized, compressed (with deflate), base64-encoded and saved as a comment in a `.php` file.
- Even if the server does not support `.htaccess` files, the data file will still not be readable by URL.
- The database looks like this:
-```php
-<?php /* zP1ZjxxJtiYIvvevEPJ2lDOaLrZv7o...
-...ka7gaco/Z+TFXM2i7BlfMf8qxpaSSYfKlvqv/x8= */ ?>
-```
- Small hashes are used to make a link to an entry in Shaarli. They are unique. In fact, the date of the items (eg. `20110923_150523`) is hashed with CRC32, then converted to base64 and some characters are replaced. They are always 6 characters longs and use only `A-Z a-z 0-9 - _` and `@`.

+## Requirements
- [Apache](#apache)
- [Nginx](#nginx)
- [Proxies](#proxies)
- [See also](#see-also)
-## Prerequisites
+### Operating system and web server
-### Shaarli
- A web server and PHP interpreter module/service have been installed.
+Shaarli can be hosted on dedicated/virtual servers, or shared hosting.
- You have write access to the Shaarli installation directory.
- The correct read/write permissions have been granted to the web server user and group.
+You need write access to the Shaarli installation directory - you should have received instructions from your hosting provider on how to connect to the server using SSH (or FTP for shared hosts).
- Your PHP interpreter is compatible with supported PHP versions:
+Examples in this documentation are given for [Debian](https://www.debian.org/), a GNU/Linux distribution widely used in server environments. Please adapt them to your specific Linux distribution.
+A $5/month VPS (1 CPU, 1 GiB RAM and 25 GiB SSD) will run any Shaarli installation without problems. Some hosting providers: [DigitalOcean](https://www.digitalocean.com/) ([1](https://www.digitalocean.com/docs/droplets/overview/), [2](https://www.digitalocean.com/pricing/), [3](https://www.digitalocean.com/docs/droplets/how-to/create/), [4](https://www.digitalocean.com/docs/droplets/how-to/add-ssh-keys/), [5](https://www.digitalocean.com/community/tutorials/initial-server-setup-with-debian-8), [6](https://www.digitalocean.com/community/tutorials/an-introduction-to-securing-your-linux-vps)), [Gandi](https://www.gandi.net/en), [OVH](https://www.ovh.co.uk/), [RackSpace](https://www.rackspace.com/), etc.
+### Network and domain name
+Try to host the server in a region that is geographically close to your users.
+A **domain name** ([DNS record](https://opensource.com/article/17/4/introduction-domain-name-system-dns)) pointing to the server's public IP address is required to obtain a SSL/TLS certificate and setup HTTPS to secure client traffic to your Shaarli instance.
+You can obtain a domain name from a [registrar](https://en.wikipedia.org/wiki/Domain_name_registrar) ([1](https://www.ovh.co.uk/domains), [2](https://www.gandi.net/en/domain)), or from free subdomain providers ([1](https://freedns.afraid.org/)). If you don't have a domain name, please set up a private domain name ([FQDN](ttps://en.wikipedia.org/wiki/Fully_qualified_domain_name)) in your clients' [hosts files](https://en.wikipedia.org/wiki/Hosts_(file)) to access the server (direct access by IP address can result in unexpected behavior).
+Setup a **firewall** (using `iptables`, [ufw](https://www.digitalocean.com/community/tutorials/how-to-set-up-a-firewall-with-ufw-on-debian-10), [fireHOL](https://firehol.org/) or any frontend of your choice) to deny all incoming traffic except `tcp/80` and `tcp/443`, which are needed to access the web server (and any other posrts you might need, like SSH). If the server is in a private network behind a NAT, ensure these **ports are forwarded** to the server.
+Shaarli makes outbound HTTP/HTTPS connections to websites you bookmark to fetch page information (title, thumbnails), the server must then have access to the Internet as well, and a working DNS resolver.

Here is an easy way to create a signed certificate using `certbot`, it assumes `certbot` was installed through APT on a Debian-based distribution:
- * Stop the apache2/nginx service.
+We recommend setting up [HTTPS](https://en.wikipedia.org/wiki/HTTPS) (SSL/[TLS](https://en.wikipedia.org/wiki/Transport_Layer_Security)) on your webserver for secure communication between clients and the server.
- * Run `certbot --agree-tos --standalone --preferred-challenges tls-sni --email "youremail@example.com" --domain yourdomain.example.com`
- * For the Apache webserver, copy `/usr/lib/python2.7/dist-packages/certbot_apache/options-ssl-apache.conf` to `/etc/letsencrypt/options-ssl-apache.conf` (paths may vary depending on installation method)
- * For Nginx: TODO
- * Setup your webserver as described below
- * Restart the apache2/nginx service.
-#### Self-signed certificates
+### Let's Encrypt
-If you don't want to request a certificate from Let's Encrypt, or are unable to (for example, webserver on a LAN, or domain name not registered in the public DNS system), you can generate a self-signed certificate. This certificate will trigger security warnings in web browsers, unless you add it to the browser's SSL store manually.
+For public-facing web servers this can be done using free SSL/TLS certificates from [Let's Encrypt](https://en.wikipedia.org/wiki/Let's_Encrypt), a non-profit certificate authority provididing free certificates.

--------------------------------------------------------------------------------
+In short:
-## Apache
+```bash
+# install certbot
+sudo apt install certbot
-Here is a basic configuration example for the Apache web server with `mod_php`.
+# stop your webserver if you already have one running
+# certbot in standalone mode needs to bind to port 80 (only needed on initial generation)
+sudo systemctl stop apache2
+sudo systemctl stop nginx
-In `/etc/apache2/sites-available/shaarli.conf`:
+# generate initial certificates
+# Let's Encrypt ACME servers must be able to access your server! port forwarding and firewall must be properly configured
+sudo certbot certonly --standalone --noninteractive --agree-tos --email "admin@shaarli.mydomain.org" -d shaarli.mydomain.org
+# this will generate a private key and certificate at /etc/letsencrypt/live/shaarli.mydomain.org/{privkey,fullchain}.pem
-```apache
+# restart the web server
-<VirtualHost *:443>
+sudo systemctl start apache2
-    ServerName   shaarli.my-domain.org
+sudo systemctl start nginx
-    DocumentRoot /absolute/path/to/shaarli/
+```
-    # Logging
+On apache `2.4.43+`, you can also delegate LE certificate management to [mod_md](https://httpd.apache.org/docs/2.4/mod/mod_md.html) [[1](https://www.cyberciti.biz/faq/how-to-secure-apache-with-mod_md-lets-encrypt-on-ubuntu-20-04-lts/)] in which case you don't need certbot and manual SSL configuration in virtualhosts.
-    # Possible values include: debug, info, notice, warn, error, crit, alert, emerg.
-    LogLevel  warn
-    ErrorLog  /var/log/apache2/shaarli-error.log
-    CustomLog /var/log/apache2/shaarli-access.log combined
-    # Let's Encrypt SSL configuration (recommended)
+### Self-signed
-    SSLEngine             on
-    SSLCertificateFile    /etc/letsencrypt/live/yourdomain.example.com/fullchain.pem
-    SSLCertificateKeyFile /etc/letsencrypt/live/yourdomain.example.com/privkey.pem
-    Include /etc/letsencrypt/options-ssl-apache.conf
-    # Self-signed SSL cert configuration
+If you don't want to rely on a certificate authority, or the server can only be accessed from your own network, you can also generate self-signed certificates. Not that this will generate security warnings in web browsers/clients trying to access Shaarli:
-    #SSLEngine             on
-    #SSLCertificateFile    /etc/ssl/certs/ssl-cert-snakeoil.pem

+The following examples assume a Debian-based operating system is installed. On other distributions you may have to adapt details such as package installation procedures, configuration file locations, and webserver username/group (`www-data` or `httpd` are common values). In these examples we assume the document root for your web server/virtualhost is at `/var/www/shaarli.mydomain.org/`:
-        #Header set Content-Security-Policy "script-src 'self' 'unsafe-inline' https://www.youtube.com https://s.ytimg.com 'unsafe-eval'"
-    </Directory>
-</VirtualHost>
+```bash
+# create the document root (replace with your own domain name)
+sudo mkdir -p /var/www/shaarli.mydomain.org/
 ```
-Enable this configuration with `sudo a2ensite shaarli`
+You can install Shaarli at the root of your virtualhost, or in a subdirectory as well. See [Directory structure](Directory-structure)
-_Note: If you use Apache 2.2 or lower, you need [mod_version](https://httpd.apache.org/docs/current/mod/mod_version.html) to be installed and enabled._
-_Note: Apache module `mod_rewrite` must be enabled to use the REST API._
+### Apache
+```bash
+# Install apache + mod_php and PHP modules
+sudo apt update
+sudo apt install apache2 libapache2-mod-php php-json php-mbstring php-gd php-intl php-curl php-gettext
-## Nginx
+# Edit the virtualhost configuration file with your favorite editor (replace the example domain name)
+sudo nano /etc/apache2/sites-available/shaarli.mydomain.org.conf
+```
-Here is a basic configuration example for the Nginx web server, using the [php-fpm](http://php-fpm.org) PHP FastCGI Process Manager, and Nginx's [FastCGI](https://en.wikipedia.org/wiki/FastCGI) module.

-## Proxies
+By default Shaarli already disallows indexing of your local copy of the documentation by default, using `<meta name="robots">` HTML tags. Your Shaarli instance may still be indexed by various robots on the public Internet, that do not respect this header or the robots standard.
-If Shaarli is served behind a proxy (i.e. there is a proxy server between clients and the web server hosting Shaarli), please refer to the proxy server documentation for proper configuration. In particular, you have to ensure that the following server variables are properly set:
- `X-Forwarded-Proto`
+- [Robots exclusion standard](https://en.wikipedia.org/wiki/Robots_exclusion_standard)
- `X-Forwarded-Host`
+- [Introduction to robots.txt](https://support.google.com/webmasters/answer/6062608?hl=en)

+- [About robots.txt](http://www.robotstxt.org)
+- [About the robots META tag](https://www.robotstxt.org/meta.html)
-In you [Shaarli configuration](Shaarli-configuration) `data/config.json.php`, add the public IP of your proxy under `security.trusted_proxies`.

-## Robots and crawlers
+[fail2ban](http://www.fail2ban.org/wiki/index.php/Main_Page) is an intrusion prevention framework that reads server (Apache, SSH, etc.) and uses `iptables` profiles to block brute-force attempts. You need to create a filter to detect shaarli login failures in logs, and a jail configuation to configure the behavior when failed login attempts are detected:
-Shaarli disallows indexing and crawling of your local documentation pages by search engines, using `<meta name="robots">` HTML tags.
+```ini
-Your Shaarli instance and other pages you host may still be indexed by various robots on the public Internet.

-## php.ini
-PHP settings are defined in:
- a main configuration file, usually found under `/etc/php/$php_version/php.ini`; some distributions provide different configuration environments, e.g.
-    - `/etc/php/$php_version/cli/php.ini` - used when running console scripts
-    - `/etc/php/$php_version/apache2/php.ini` - used when a client requests PHP resources from Apache
-    - `/etc/php/$php_version/php-fpm.conf` - used when PHP requests are proxied to PHP-FPM
- additional configuration files/entries, depending on the installed/enabled extensions:
-    - `/etc/php/conf.d/xdebug.ini`
-### Locate .ini files
-#### Console environment
-```bash

-## Foreword
+# Shaarli configuration
-**Do not edit configuration options in index.php! Your changes would be lost.** 
 Once your Shaarli instance is installed, the file `data/config.json.php` is generated:
-* it contains all settings in JSON format, and can be edited to customize values
-* it defines which [plugins](Plugin-System) are enabled
-* its values override those defined in `index.php`
-* it is wrap in a PHP comment to prevent anyone accessing it, regardless of server configuration
-## File and directory permissions
-The server process running Shaarli must have:
- `read` access to the following resources:
-    - PHP scripts: `index.php`, `application/*.php`, `plugins/*.php`
-    - 3rd party PHP and Javascript libraries: `inc/*.php`, `inc/*.js`
-    - static assets:
-        - CSS stylesheets: `inc/*.css`
-        - `images/*`
-    - RainTPL templates: `tpl/*.html`
- `read`, `write` and `execution` access to the following directories:
-    - `cache` - thumbnail cache
-    - `data` - link data store, configuration options
-    - `pagecache` - Atom/RSS feed cache
-    - `tmp` - RainTPL page cache
-On a Linux distribution:
- the web server user will likely be `www` or `http` (for Apache2)
- it will be a member of a group of the same name: `www:www`, `http:http`
- to give it access to Shaarli, either:
-    - unzip Shaarli in the default web server location (usually `/var/www/`) and set the web server user as the owner
-    - put users in the same group as the web server, and set the appropriate access rights
- if you have a domain / subdomain to serve Shaarli, [configure the server](Server-configuration) accordingly

-Content posted to Shaarli is separated in items called _Shaares_. For each Shaare,
-you can customize the following aspects:
- * URL to link to
- * Title
- * Free-text description
- * Tags
- * Public/private status
--------------------------------------------------------------------------------
-## Adding new Shaares
-While logged in to your Shaarli, you can add new Shaares in several ways:
- * [+Shaare button](#shaare-button)
- * [Bookmarklet](#bookmarklet)
- * Third-party [apps and browser addons](Community-&-Related-software.md#mobile-apps)
- * [REST API](https://shaarli.github.io/api-documentation/)
-### +Shaare button
- * While logged in to your Shaarli, click the **`+Shaare`** button located in the toolbar.
- * Enter the URL of a link you want to share.
- * Click `Add link`
- * The `New Shaare` dialog appears, allowing you to fill in the details of your Shaare.
-   * The Description, Title, and Tags will help you find your Shaare later using tags or full-text search.
-   * You can also check the “Private” box so that the link is saved but only visible to you (the logged-in user).
- * Click `Save`.
-<!-- TODO Add screenshot of add/edit link dialog -->
-### Bookmarklet
-The _Bookmarklet_ \[[1](https://en.wikipedia.org/wiki/Bookmarklet)\] is a special
-browser bookmark you can use to add new content to your Shaarli. This bookmarklet is
-compatible with Firefox, Opera, Chrome and Safari. To set it up:
- * Access the `Tools` page from the button in the toolbar.
- * Drag the **`✚Shaare link` button** to your browser's bookmarks bar.
-Once this is done, you can shaare any URL you are visiting simply by clicking the
-bookmarklet in your browser! The same `New Shaare` dialog as above is displayed.
-| Note | Websites which enforce Content Security Policy (CSP), such as github.com, disallow usage of bookmarklets. Unfortunately, there is nothing Shaarli can do about it. \[[1](https://github.com/shaarli/Shaarli/issues/196)]\ \[[2](https://bugzilla.mozilla.org/show_bug.cgi?id=866522)]\ \[[3](https://code.google.com/p/chromium/issues/detail?id=233903)]\ |

-| Note | Under Opera, you can't drag'n drop the button: You have to right-click on it and add a bookmark to your personal toolbar. |
-|---------|---------|
-![](images/bookmarklet.png)
--------------------------------------------------------------------------------
-## Editing Shaares
-Any Shaare can edited by clicking its ![](images/edit_icon.png) `Edit` button.
-Editing a Shaare will not change it's permalink, each permalink always points to the
-latest revision of a Shaare.
--------------------------------------------------------------------------------
-## Using shaarli as a blog, notepad, pastebin...
-While adding or editing a link, leave the URL field blank to create a text-only
-("note") post. This allows you to post any kind of text content, such as blog
-articles, private or public notes, snippets... There is no character limit! You can
-access your Shaare from its permalink.

 ## Browser issues
 ### Redirection issues (HTTP Referer)
-Depending on its configuration and installed plugins, the browser may remove or alter (spoof) [HTTP referers](https://en.wikipedia.org/wiki/HTTP_referer), thus preventing Shaarli from properly redirecting between pages. Referer settings are available by browsing `about:config` and are documented [here](https://wiki.mozilla.org/Security/Referrer). `network.http.referer.spoofSource = true` in particular is known to break some functionality in Shaarli.
+Shaarli relies on `HTTP_REFERER` for some functions (like redirects and clicking on tags). If you have disabled or altered/spoofed [HTTP referers](https://en.wikipedia.org/wiki/HTTP_referer) in your browser, some features of Shaarli may not work as expected (depending on configuration and installed plugins), notably redirections between pages.
+Firefox Referer settings are available by browsing `about:config` and are documented [here](https://wiki.mozilla.org/Security/Referrer). `network.http.referer.spoofSource = true` in particular is known to break some functionality in Shaarli.
 ### Firefox, localhost and redirections
 `localhost` is not a proper Fully Qualified Domain Name (FQDN); if Firefox has been set up to spoof referers, or only accept requests from the same base domain/host,
 Shaarli redirections will not work properly. To solve this, assign a local domain to your host, e.g. `localhost.lan` in your [hosts file](https://en.wikipedia.org/wiki/Hosts_(file)) and browse Shaarli at http://localhost.lan/.

+You may be interested in these Firefox addons to manage bookmarks imported from Shaarli
+- [Bookmark Deduplicator](https://addons.mozilla.org/en-US/firefox/addon/bookmark-deduplicator/) - provides an easy way to deduplicate your bookmarks
+- [TagSieve](https://addons.mozilla.org/en-US/firefox/addon/tagsieve/) - browse your bookmarks by their tags
+### Diigo
+If you export your bookmark from Diigo, make sure you use the Delicious export, not the Netscape export. (Their Netscape export is broken, and they don't seem to be interested in fixing it.)
+### Mister Wong
+See [this issue](https://github.com/sebsauvage/Shaarli/issues/146) for import tweaks.
+### SemanticScuttle
+To correctly import the tags from a [SemanticScuttle](http://semanticscuttle.sourceforge.net/) HTML export, edit the HTML file before importing and replace all occurences of `tags=` (lowercase) to `TAGS=` (uppercase).
+### Scuttle
+Shaarli cannot import data directly from [Scuttle](https://github.com/scronide/scuttle).
+However, you can use the third-party [scuttle-to-shaarli](https://github.com/q2apro/scuttle-to-shaarli)
+tool to export the Scuttle database to the Netscape HTML format compatible with the Shaarli importer.
+### Refind.com
+You can use the third-party tool [Derefind](https://github.com/ShawnPConroy/Derefind) to convert refind.com bookmark exports to a format that can be imported into Shaarli.
+-------------------------------------------------------
+## Other
+### The bookmarklet doesn't work
+Websites which enforce Content Security Policy (CSP), such as github.com, disallow usage of bookmarklets. Unfortunately, there is nothing Shaarli can do about it ([1](https://github.com/shaarli/Shaarli/issues/196), [2](https://bugzilla.mozilla.org/show_bug.cgi?id=866522), [3](https://code.google.com/p/chromium/issues/detail?id=233903).
+Under Opera, you can't drag'n drop the button: You have to right-click on it and add a bookmark to your personal toolbar.
+### Changing the timestamp for a shaare
+- Look for `<input type="hidden" name="lf_linkdate" value="{$link.linkdate}">` in `tpl/editlink.tpl` (line 14)
+- Replace `type="hidden"` with `type="text"` from this line
+- A new date/time field becomes available in the edit/new Shaare dialog.
+- You can set the timestamp manually by entering it in the format `YYYMMDD_HHMMS`.
+### Clearing Shaarli caches
+For debugging purposes:
+```bash
+# clear raintpl cache and temporary files
+find /var/www/links/cache/ /var/www/links/pagecache/ /var/www/links/tmp/ -type f -exec rm -v '{}' \;
+# if you have a php accelerator such as php-apcu, restart the webserver
+sudo systemctl restart apache2

-The testing framework used is [PHPUnit](https://phpunit.de/); it can be installed with [Composer](https://getcomposer.org/), which is a dependency management tool.
-## Setup a testing environment
-### Install composer
-You can either use:
- a system-wide version, e.g. installed through your distro's package manager (eg. `sudo apt install composer`)
- a local version, downloadable [here](https://getcomposer.org/download/). To update a local composer installation, run `php composer.phar self-update`
-### Install Shaarli development dependencies
-```bash
-$ cd /path/to/shaarli
-$ composer install
-```
-### Install Xdebug
-Xdebug must be installed and enable for PHPUnit to generate coverage reports. See http://xdebug.org/docs/install.
-```bash
-# for Debian-based distributions
-$ aptitude install php-xdebug
-# for ArchLinux:
-$ pacman -S xdebug
-```
-Then add the following line to `/etc/php/<PHP_VERSION>/cli/php.ini`:
-```ini
-zend_extension=xdebug.so
-```
-## Run unit tests
-Run `make test` and ensure tests return `OK`. If tests return failures, refer to PHPUnit messages and fix your code/tests accordingly.
-By default, PHPUnit will run all suitable tests found under the `tests` directory. Each test has 3 possible outcomes:
- `.` - success
- `F` - failure: the test was run but its results are invalid
-    - the code does not behave as expected
-    - dependencies to external elements: globals, session, cache...
- `E` - error: something went wrong and the tested code has crashed
-    - typos in the code, or in the test code
-    - dependencies to missing external elements
-If Xdebug has been installed and activated, two coverage reports will be generated:
- a summary in the console
- a detailed HTML report with metrics for tested code
-    - to open it in a web browser: `firefox coverage/index.html &`
-### Executing specific tests
-Add a [`@group`](https://phpunit.de/manual/current/en/appendixes.annotations.html#appendixes.annotations.group) annotation in a test class or method comment:
-```php
-/**
- * Netscape bookmark import
- * @group WIP
- */
-class BookmarkImportTest extends PHPUnit_Framework_TestCase
-{
-   [...]
-}
-```
-To run all tests annotated with `@group WIP`:
-```bash
-$ vendor/bin/phpunit --group WIP tests/
-```
-### Running tests inside Docker containers
-Test Dockerfiles are located under `tests/docker/<distribution>/Dockerfile`,
-and can be used to build Docker images to run Shaarli test suites under common
-Linux environments.
-Dockerfiles are provided for the following environments:
- `alpine36` - [Alpine 3.6](https://www.alpinelinux.org/downloads/)
- `debian8` - [Debian 8 Jessie](https://www.debian.org/DebianJessie) (oldstable)
- `debian9` - [Debian 9 Stretch](https://wiki.debian.org/DebianStretch) (stable)
- `ubuntu16` - [Ubuntu 16.04 Xenial Xerus](http://releases.ubuntu.com/16.04/) (LTS)
-What's behind the curtains:
- each image provides:
-    - a base Linux OS
-    - Shaarli PHP dependencies (OS packages)
-    - test PHP dependencies (OS packages)
-    - Composer
- the local workspace is mapped to the container's `/shaarli/` directory,
- the files are rsync'd so tests are run using a standard Linux user account
-  (running tests as `root` would bypass permission checks and may hide issues)
- the tests are run inside the container.
-To run tests inside a Docker container:
-```bash
-# build the Debian 9 Docker image for unit tests
-$ cd /path/to/shaarli
-$ cd tests/docker/debian9
-$ docker build -t shaarli-test:debian9 .
-# install/update 3rd-party test dependencies
-$ composer install --prefer-dist
-# run tests using the freshly built image
-$ docker run -v $PWD:/shaarli shaarli-test:debian9 docker_test
-# run the full test campaign
-$ docker run -v $PWD:/shaarli shaarli-test:debian9 docker_all_tests

+## Features
+For any item posted to Shaarli (called a _Shaare_), you can customize the following aspects:
+- URL to link to
+- Title
+- Free-text description
+- Tags
+- Public/private status
+### Adding/editing Shaares
+While logged in to your Shaarli, you can add, edit or delete Shaares:
+- Using the **+Shaare** button: enter the URL you want to share, click `Add link`, fill in the details of your Shaare, and `Save`
+- Using the [Bookmarklet](https://en.wikipedia.org/wiki/Bookmarklet): drag the `✚Shaare link` button from the `Tools` page to your browser's bookmarks bar, click it to share the current page.
+- Using [apps and browser addons](Community-and-related-software.md#mobile-apps)
+- Using the [REST API](https://shaarli.github.io/api-documentation/)
+- Any Shaare can edited by clicking its ![](images/edit_icon.png) `Edit` button.
+### Tags
+Tags can be be used to organize and categorize your Shaares:
+- You can rename, merge and delete tags from the _Tools_ menu or the [tag cloud/list](#tag-cloud)
+- Tags are auto-completed (from the list of existing tags) in all dialogs
+- Tags can be combined with text in [search](#search) queries
+### Public/private Shaares
+Additional filter buttons can be found at the top left of the Shaare list **only when logged in**:
+- **Only show private Shaares:** Private shares can be searched by clicking the `only show private links` toggle button top left of the Shaares list (only when logged in)
+### Permalinks
+Permalinks are fixed, short links attached to each Shaare. Editing a Shaare will not change it's permalink, each permalink always points to the latest revision of a Shaare.
+### Text-only (note) Shaares
+Shaarli can be used as a minimal blog, notepad, pastebin...: While adding or editing a Shaare, leave the URL field blank to create a text-only ("note") post. This allows you to post any kind of text content, such as blog articles, private or public notes, snippets... There is no character limit! You can access your post from its permalink.

+- **Plain text search:** Use `Search text` to search in all fields of all Shaares (Title, URL, Description...). Use double-quotes (example `"exact search"`) to search for the exact expression.
+- **Tags search:** `Filter by tags` allow only displaying Shaares tagged with one or multiple tags (use space to separate tags).
+- **Hidden tags:** tags starting with a dot `.` (example `.secret`) are private. They can only be seen and searched when logged in.
+- **Exclude text/tags:** Use the `-` operator before a word or tag to exclude Shaares matching this word from search results (`NOT` operator).
+- **Untagged links:** Shaares without tags can be searched by clicking the `untagged` toggle button top left of the Shaares list (only when logged in).
+Both exclude patterns and exact searches can be combined with normal searches (example `"exact search" term otherterm -notthis "very exact" stuff -notagain`). Only AND (and NOT) search is currrently supported.
+Active search terms are displayed on top of the link list. To remove terms/tags from the curent search, click the `x` next to any of them, or simply clear text/tag search fields.
+### Tag cloud
+The `Tag cloud` page diplays a "cloud" or list view of all tags in your Shaarli (most frequently used tags are displayed with a bigger font size)
+- **Tags list:** click on `Most used` or `Alphabetical` to display tags as a list. You can also edit/delete tags for this page.
+- Click on any tag to search all Shaares matching this tag.
+- **Filtering the tag cloud/list:** Click on the counter next to a tag to show other tags of Shaares with this tag. Repeat this any number of times to further filter the tag cloud. Click `List all links with those tags` to display Shaares matching your current tag filter set.
+### RSS feeds
+RSS/ATOM feeds feeds are available (in ATOM with `/feed/atom` and RSS with `/feed/rss`)
+- **Filtering RSS feeds:** RSS feeds and picture wall can also be restricted to only return items matching a text/tag search. For example, search for `photography` (text or tags) in Shaarli, then click the `RSS Feed` button. A feed with only matching results is displayed.
+- Add the `&nb` parameter in feed URLs to specify the number of Shaares you want in a feed (default if not specified: `50`). The keyword `all` is available if you want everything.
+- Add the `&permalinks` parameter in feed URLs to point permalinks to the corresponding shaarly entry/link instead of the direct, Shaare URL attribute
+![](images/rss-filter-1.png) ![](images/rss-filter-2.png)
+```bash
+# examples
+https://shaarli.mydomain.org/feed/atom?permalinks
+https://shaarli.mydomain.org/feed/atom?permalinks&nb=42
+https://shaarli.mydomain.org/feed/atom?permalinks&nb=all
+https://shaarli.mydomain.org/feed/rss?searchtags=nature
+https://shaarli.mydomain.org/links/picture-wall?searchterm=poney
+```
+### Picture wall
+- The picture wall can be filtered by text or tags search in the same way as [RSS feeds](#rss-feeds)
+### Import/export
+To **export Shaares as a HTML file**, under _Tools > Export_, choose:
+- `Export all` to export both public and private Shaares
+- `Export public` to export public Shaares only
+- `Export private` to export private Shaares only
+Restore by using the `Import` feature.
+- These exports contain the full data (URL, title, tags, date, description, public/private status of your Shaares)
+- They can also be imported to your web browser bookmarks.
+To **import a HTML bookmarks file** exported from your browser, just use the `Import` feature. For each "folder" in the bookmarks you imported, a new tag will be created (for example a bookmark in `Movies > Sci-fi` folder will be tagged `Movies` `Sci-fi`).

+# Development
+Please read [Contributing to Shaarli](https://github.com/shaarli/Shaarli/tree/master/CONTRIBUTING.md)
+## Guidelines
+- [Unit tests](Unit-tests)
+- Javascript linting - Shaarli uses [Airbnb JavaScript Style Guide](https://github.com/airbnb/javascript). 
+Run `make eslint` to check JS style.
+- [GnuPG signature](GnuPG-signature) for tags/releases
+## Third-party libraries
+CSS:
+- Yahoo UI [CSS Reset](http://yuilibrary.com/yui/docs/cssreset/) - standardize cross-browser rendering
+Javascript:
+- [Awesomeplete](https://leaverou.github.io/awesomplete/) ([GitHub](https://github.com/LeaVerou/awesomplete)) - autocompletion in input forms
+- [bLazy](http://dinbror.dk/blazy/) ([GitHub](https://github.com/dinbror/blazy)) - lazy loading for thumbnails
+- [qr.js](http://neocotic.com/qr.js/) ([GitHub](https://github.com/neocotic/qr.js)) - QR code generation
+PHP (managed through [`composer.json`](https://github.com/shaarli/Shaarli/blob/master/composer.json)):
+- [RainTPL](https://github.com/rainphp/raintpl) - HTML templating for PHP
+- [`shaarli/netscape-bookmark-parser`](https://packagist.org/packages/shaarli/netscape-bookmark-parser) - Import bookmarks from Netscape files
+- [`erusev/parsedown`](https://packagist.org/packages/erusev/parsedown) - Parse MarkDown syntax for the MarkDown plugin
+- [`slim/slim`](https://packagist.org/packages/slim/slim) - Handle routes and middleware for the REST API
+- [`ArthurHoaro/web-thumbnailer`](https://github.com/ArthurHoaro/web-thumbnailer) - PHP library which will retrieve a thumbnail for any given URL
+- [`pubsubhubbub/publisher`](https://github.com/pubsubhubbub/php-publisher) - A PubSubHubbub publisher module for PHP.
+- [`gettext/gettext`](https://github.com/php-gettext/Gettext) - PHP library to collect and manipulate gettext (.po, .mo, .php, .json, etc)
+## Security
+- The password is salted, hashed and stored in the data subdirectory, in a PHP file, and protected by htaccess. Even if the webserver does not support htaccess, the hash is not readable by URL. Even if the .php file is stolen, the password cannot deduced from the hash. The salt prevents rainbow-tables attacks.
+- Directories are protected using `.htaccess` files
+- Forms are protected against [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery):
+    - Forms which act on data (save,delete…) contain a token generated by the server.
+    - Any posted form which does not contain a valid token is rejected.
+    - Any token can only be used once.
+    - Tokens are attached to the session and cannot be reused in another session.
+- Sessions automatically expire after 60 minutes.
+- Sessions are protected against hijacking: the session ID cannot be used from a different IP address.
+- Links are stored as an associative array which is serialized, compressed (with deflate), base64-encoded and saved as a comment in a `.php` file - even if the server does not support `.htaccess` files, the data file will still not be readable by URL.
+- Bruteforce protection: Successful and failed login attempts are logged - IP bans are enforced after a configurable amount of failures. Logs can also be used consumed by [fail2ban](../Server-configuration.md#fail2ban)
+- A pop-up notification is shown when a new release is available.
+## Link structure
+Every link available through the `LinkDB` object is represented as an array 
+containing the following fields:
+  * `id` (integer): Unique identifier.
+  * `title` (string): Title of the link.
+  * `url` (string): URL of the link. Used for displayable links (without redirector, url encoding, etc.).  
+           Can be absolute or relative for Notes.
+  * `real_url` (string): Real destination URL, can be redirected, encoded, etc.
+  * `shorturl` (string): Permalink small hash.
+  * `description` (string): Link text description.
+  * `private` (boolean): whether the link is private or not.
+  * `tags` (string): all link tags separated by a single space
+  * `thumbnail` (string|boolean): relative path of the thumbnail cache file, or false if there isn't any.
+  * `created` (DateTime): link creation date time.
+  * `updated` (DateTime): last modification date time.
+  
+Small hashes are used to make a link to an entry in Shaarli. They are unique: the date of the item (eg. `20110923_150523`) is hashed with CRC32, then converted to base64 and some characters are replaced. They are always 6 characters longs and use only `A-Z a-z 0-9 - _` and `@`.

+Shaarli needs read access to:
+- the root index.php file
+- the `application/`, `plugins/` and `inc/` directories (recursively)
+Shaarli needs read/write access to the `cache/`, `data/`, `pagecache/`, and `tmp/` directories
+## Automation
+A [`Makefile`](https://github.com/shaarli/Shaarli/blob/master/Makefile) is available to perform project-related operations:
+- [Static analysis](#Static-analysis) - check that the code is compliant to PHP conventions
+- [Unit tests](#Unit-tests) - ensure there are no regressions introduced by new commits
+- Documentation - generate a local HTML copy of the markdown documentation
+### Continuous Integration
+[Travis CI](http://docs.travis-ci.com/) is a Continuous Integration build server, that runs a build:
+- each time a commit is merged to the mainline (`master` branch)
+- each time a Pull Request is submitted or updated
+After all jobs have finished, Travis returns the results to GitHub:
+- a status icon represents the result for the `master` branch: [![](https://api.travis-ci.org/shaarli/Shaarli.svg)](https://travis-ci.org/shaarli/Shaarli)
+- Pull Requests are updated with the Travis build result.
+See [`.travis.yml`](https://github.com/shaarli/Shaarli/blob/master/.travis.yml).
+### Documentation
+[mkdocs](https://www.mkdocs.org/) is used to convert markdown documentation to HTML pages. The [public documentation](https://shaarli.readthedocs.io/en/master/) website is rendered and hosted by [readthedocs.org](https://readthedocs.org/). A copy of the documentation is also included in prebuilt [release archives](https://github.com/shaarli/Shaarli/releases) (`doc/html/` path in your Shaarli installation). To generate the HTML documentation locally, install a recent version of Python `setuptools` and run    `make doc`.
+## Static analysis
+Patches should try to stick to the [PHP Standard Recommendations](http://www.php-fig.org/psr/) (PSR), especially:
+- [PSR-1](http://www.php-fig.org/psr/psr-1/) - Basic Coding Standard
+- [PSR-2](http://www.php-fig.org/psr/psr-2/) - Coding Style Guide
+**Work in progress:** Static analysis is currently being discussed here: in [#95 - Fix coding style (static analysis)](https://github.com/shaarli/Shaarli/issues/95), [#130 - Continuous Integration tools & features](https://github.com/shaarli/Shaarli/issues/130)
+Static analysis tools can be installed with Composer, and used through Shaarli's [Makefile](https://github.com/shaarli/Shaarli/blob/master/Makefile).
+For an overview of the available features, see:
+- [Code quality: Makefile to run static code checkers](https://github.com/shaarli/Shaarli/pull/124) (#124)
+- [Run PHPCS against different coding standards](https://github.com/shaarli/Shaarli/pull/276) (#276)

+# Release Shaarli
+## Requirements
+This guide assumes that you have:
+- a GPG key matching your GitHub authentication credentials/email (the email address identified by the GPG key is the same as the one in your `~/.gitconfig`)
+- a GitHub fork of Shaarli
+- a local clone of your Shaarli fork, with the following remotes:
+    - `origin` pointing to your GitHub fork
+    - `upstream` pointing to the main Shaarli repository
+- maintainer permissions on the main Shaarli repository, to:
+    - push the signed tag
+    - create a new release
+- [Composer](https://getcomposer.org/) needs to be installed
+- The [venv](https://docs.python.org/3/library/venv.html) Python 3 module needs to be installed for HTML documentation generation.
+## Release notes and `CHANGELOG.md`
+GitHub allows drafting the release notes for the upcoming release, from the [Releases](https://github.com/shaarli/Shaarli/releases) page. This way, the release note can be drafted while contributions are merged to `master`. See http://keepachangelog.com/en/0.3.0/ for changelog formatting.
+`CHANGELOG.md` should contain the same information as the release note draft for the upcoming version. Update it to:
+- add new entries (additions, fixes, etc.)
+- mark the current version as released by setting its date and link
+- add a new section for the future unreleased version
+```bash
+## [v0.x.y](https://github.com/shaarli/Shaarli/releases/tag/v0.x.y) - UNRELEASES
+### Added
+### Changed
+### Fixed
+### Removed
+### Deprecated
+### Security
+```
+## Update the list of Git contributors
+```bash
+$ make authors
+$ git commit -s -m "Update AUTHORS"
+```
+## Create and merge a Pull Request
+Create a Pull Request to marge changes from your remote, into `master` in the community Shaarli repository, and have it merged.
+## Create the release branch and update shaarli_version.php
+```bash
+# fetch latest changes from master to your local copy
+git checkout master
+git pull upstream master
+# If releasing a new minor version, create a release branch
+$ git checkout -b v0.x
+# Bump shaarli_version.php from dev to 0.x.0, **without the v**
+$ vim shaarli_version.php
+$ git add shaarli_version
+$ git commit -s -m "Bump Shaarli version to v0.x.0"
+$ git push upstream v0.x
+```
+## Create and push a signed tag
+Git [tags](http://git-scm.com/book/en/v2/Distributed-Git-Maintaining-a-Project#Tagging-Your-Releases) are used to identify specific revisions with a unique version number that follows [semantic versioning](https://semver.org/)
+```bash
+# update your local copy
+git checkout v0.5
+git pull upstream v0.5
+# create a signed tag
+git tag -s -m "Release v0.5.0" v0.5.0
+# push the tag to upstream
+git push --tags upstream
+```
+Here is how to verify a signed tag. [`v0.5.0`](https://github.com/shaarli/Shaarli/releases/tag/v0.5.0) is the first GPG-signed tag pushed on the Community Shaarli. Let's have a look at its signature!
+```bash
+# update the list of available tags
+git fetch upstream
+# get the SHA1 reference of the tag
+git show-ref tags/v0.5.0
+# gives: f7762cf803f03f5caf4b8078359a63783d0090c1 refs/tags/v0.5.0
+# verify the tag signature information
+git verify-tag f7762cf803f03f5caf4b8078359a63783d0090c1
+# gpg: Signature made Thu 30 Jul 2015 11:46:34 CEST using RSA key ID 4100DF6F
+# gpg: Good signature from "VirtualTam <virtualtam@flibidi.net>" [ultimate]
+```
+## Publish the GitHub release
+- In the `master` banch, update version badges in `README.md` to point to the newly released Shaarli version
+- Update the previously drafted [release](https://github.com/shaarli/Shaarli/releases) (notes, tag) and publish it
+- Profit!
+## Generate full release zip archives
+Release archives will contain Shaarli code plus all required third-party libraries. They are useful for users who:
+- have no SSH access, no possibility to install PHP packages/server extensions, no possibility to run scripts (shared hosting)
+- do not want to install build/dev dependencies on their server
+ `git checkout` the appropriate branch, then:
+```bash
+# checkout the appropriate branch
+git checkout 0.x.y
+# generate zip archives
+make release_archive
+```
+This will create `shaarli-v0.x.y-full.tar`, `shaarli-v0.x.y-full.zip`. These archives need to be manually uploaded on the previously created GitHub [release](https://github.com/shaarli/Shaarli/releases).
+### Update the `latest` branch
+```bash
+# checkout the 'latest' branch
+git checkout latest
+# merge changes from your newly published release branch
+git merge v0.x.y
+# fix eventual conflicts with git mergetool...
+# run tests
+make test
+# push the latest branch
+git push upstream latest
+```

+# Unit tests
+Shaarli uses the [PHPUnit](https://phpunit.de/) test framework; it can be installed with [Composer](https://getcomposer.org/), which is a dependency management tool.
+## Install composer
+You can either use:
+- a system-wide version, e.g. installed through your distro's package manager
+- a local version, downloadable [here](https://getcomposer.org/download/).
+```bash
+# system-wide version
+$ composer install
+$ composer update
+# local version
+$ php composer.phar self-update
+$ php composer.phar install
+$ php composer.phar update
+```
+## Install Shaarli dev dependencies
+```bash
+$ cd /path/to/shaarli
+$ composer update
+```
+## Install and enable Xdebug to generate PHPUnit coverage reports
+[Xdebug](http://xdebug.org/docs/install) is a PHP extension which provides debugging and profiling capabilities. Install Xdebug:
+```bash
+# for Debian-based distros:
+sudo aptitude install php5-xdebug
+# for ArchLinux:
+pacman -S xdebug
+# then add the following line to /etc/php/php.ini
+zend_extension=xdebug.so
+```
+## Run unit tests
+Ensure tests pass successuflly:
+```bash
+make test
+# ...
+# OK (36 tests, 65 assertions)
+```
+In case of failure the test suite will point you to actual errors and output a summary:
+```bash
+make test
+# ...
+# FAILURES!
+# Tests: 36, Assertions: 63, Errors: 1, Failures: 2.
+```
+By default, PHPUnit will run all suitable tests found under the `tests` directory. Each test has 3 possible outcomes:
+- `.` - success
+- `F` - failure: the test was run but its results are invalid
+    - the code does not behave as expected
+    - dependencies to external elements: globals, session, cache...
+- `E` - error: something went wrong and the tested code has crashed
+    - typos in the code, or in the test code
+    - dependencies to missing external elements
+If Xdebug has been installed and activated, two coverage reports will be generated:
+- a summary in the console
+- a detailed HTML report with metrics for tested code
+    - to open it in a web browser: `firefox coverage/index.html &`
+### Executing specific tests
+Add a [`@group`](https://phpunit.de/manual/current/en/appendixes.annotations.html#appendixes.annotations.group) annotation in a test class or method comment:
+```php
+/**
+ * Netscape bookmark import
+ * @group WIP
+ */
+class BookmarkImportTest extends PHPUnit_Framework_TestCase
+{
+   [...]
+}
+```
+To run all tests annotated with `@group WIP`:
+```bash
+$ vendor/bin/phpunit --group WIP tests/
+```
+## Running tests inside Docker containers
+Unit tests can be run inside [Docker](../Docker.md) containers.
+Test Dockerfiles are located under `tests/docker/<distribution>/Dockerfile`, and can be used to build Docker images to run Shaarli test suites under commonLinux environments. Dockerfiles are provided for the following environments:
+- [`alpine36`](https://github.com/shaarli/Shaarli/blob/master/tests/docker/alpine36/Dockerfile) - [Alpine Linux 3.6](https://www.alpinelinux.org/downloads/)
+- [`debian8`](https://github.com/shaarli/Shaarli/blob/master/tests/docker/debian8/Dockerfile) - [Debian 8 Jessie](https://www.debian.org/DebianJessie) (oldoldstable)
+- [`debian9`](https://github.com/shaarli/Shaarli/blob/master/tests/docker/debian9/Dockerfile) - [Debian 9 Stretch](https://wiki.debian.org/DebianStretch) (oldstable)
+- [`ubuntu16`](https://github.com/shaarli/Shaarli/blob/master/tests/docker/ubuntu16/Dockerfile) - [Ubuntu 16.04 Xenial Xerus](http://releases.ubuntu.com/16.04/) (old LTS)
+Each image provides:
+- a base Linux OS
+- Shaarli PHP dependencies (OS packages)
+- test PHP dependencies (OS packages)
+- Composer
+- Tests that run inside the conatiner using a standard Linux user account (running tests as `root` would bypass permission checks and may hide issues)
+Build a test image:
+```bash
+# build the Debian 9 Docker image
+cd /path/to/shaarli/tests/docker/debian9
+docker build -t shaarli-test:debian9 .
+```
+Run unit tests in a container:
+```bash
+cd /path/to/shaarli
+# install/update 3rd-party test dependencies
+composer install --prefer-dist
+# run tests using the freshly built image
+docker run -v $PWD:/shaarli shaarli-test:debian9 docker_test
+# run the full test campaign
+docker run -v $PWD:/shaarli shaarli-test:debian9 docker_all_tests

-It's important to understand how Shaarli branches work, especially if you're maintaining a 3rd party tools for Shaarli (theme, plugin, etc.), to be sure stay compatible.
 ## `master` branch
@@ -11,39 +12,26 @@ Remarks:
 - This branch shouldn't be used for production as it isn't necessary stable.
 - 3rd party aren't required to be compatible with the latest changes.
 - Official plugins, themes and libraries (contained within Shaarli organization repos) must be compatible with the master branch.
- The version in this branch is always `dev`.
-## `v0.x` branch
-This `v0.x` branch, points to the latest `v0.x.y` release.
+## `v0.x` branch
-Explanation:
+The `v0.x` branch points to the latest `v0.x.y` release.
-When a new version is released, it might contains a major bug which isn't detected right away. For example, a new PHP version is released, containing backward compatibility issue which doesn't work with Shaarli.
+If a major bug affects the original `v0.x.0` release, we may [backport](https://en.wikipedia.org/wiki/Backporting) a fix for this bug from master, to the `v0.x` branch, and create a new bugfix release (eg. `v0.x.1`) from this branch.
-In this case, the issue is fixed in the `master` branch, and the fix is backported the to the `v0.x` branch. Then a new release is made from the `v0.x` branch.
+This allows users of the original release to upgrade to the fixed version, without having to upgrade to a completely new minor/major release.
-This workflow allow us to fix any major bug detected, without having to release bleeding edge feature too soon.
 ## `latest` branch
 This branch point the latest release. It recommended to use it to get the latest tested changes.
-## `stable` branch
-The `stable` branch doesn't contain any major bug, and is one major digit version behind the latest release.
-For example, the current latest release is `v0.8.3`, the stable branch is an alias to the latest `v0.7.x` release. When the `v0.9.0` version will be released, the stable will move to the latest `v0.8.x` release.
-Remarks:
- Shaarli release pace isn't fast, and the stable branch might be a few months behind the latest release.
 ## Releases
-Releases are always made from the latest `v0.x` branch.
+For every release, we manually generate a .zip file which contains all Shaarli dependencies, making Shaarli's installation only one step.
-Note that for every release, we manually generate a tarball which contains all Shaarli dependencies, making Shaarli's installation only one step.

-Status: Downloaded newer image for debian:wheezy
-```
-Docker re-uses layers already downloaded. In other words if you have images based on Alpine or some Ubuntu version for example, those can share disk space.
-### Start a container
-A container is an instance created from an image, that can be run and that keeps running until its main process exits. Or until the user stops the container. 
-The simplest way to start a container from image is ``docker run``. It also pulls the image for you if it is not locally available. For more advanced use, refer to ``docker create``.
-Stopped containers are not destroyed, unless you specify ``--rm``. To view all created, running and stopped containers, enter:
-```bash
-$ docker ps -a
-```
-Some containers may be designed or configured to be restarted, others are not. Also remember both network ports and volumes of a container are created on start, and not editable later.
-### Access a running container
-A running container is accessible using ``docker exec``, or ``docker copy``. You can use ``exec`` to start a root shell in the Shaarli container:
-```bash
-$ docker exec -ti <container-name-or-id> bash
-```
-Note the names and ID's of containers are listed in ``docker ps``. You can even type only one or two letters of the ID, given they are unique.
-Access can also be through one or more network ports, or disk volumes. Both are specified on and fixed on ``docker create`` or ``run``.
-You can view the console output of the main container process too:
-```bash
-$ docker logs -f <container-name-or-id>
-```
-### Docker disk use
-Trying out different images can fill some gigabytes of disk quickly. Besides images, the docker volumes usually take up most disk space.
-If you care only about trying out docker and not about what is running or saved, the following commands should help you out quickly if you run low on disk space:
-```bash
-$ docker rmi -f $(docker images -aq) # remove or mark all images for disposal
-$ docker volume rm $(docker volume ls -q) # remove all volumes
-```
-### Systemd config
-Systemd is the process manager of choice on Debian-based distributions. Once you have a ``docker`` service installed, you can use the following steps to set up Shaarli to run on system start.
-```bash
-systemctl enable /etc/systemd/system/docker.shaarli.service
-systemctl start docker.shaarli
-systemctl status docker.*
-journalctl -f # inspect system log if needed
-```
-You will need sudo or a root terminal to perform some or all of the steps above. Here are the contents for the service file:
-```
-[Unit]
-Description=Shaarli Bookmark Manager Container
-After=docker.service
-Requires=docker.service

-## Foreword
-This guide assumes that:
- Shaarli runs in a Docker container
- The host's `10080` port is mapped to the container's `80` port
- Shaarli's Fully Qualified Domain Name (FQDN) is `shaarli.domain.tld`
- HTTP traffic is redirected to HTTPS
-## Apache
- [Apache 2.4 documentation](https://httpd.apache.org/docs/2.4/)
-    - [mod_proxy](https://httpd.apache.org/docs/2.4/mod/mod_proxy.html)
-    - [Reverse Proxy Request Headers](https://httpd.apache.org/docs/2.4/mod/mod_proxy.html#x-headers)
-The following HTTP headers are set when the `ProxyPass` directive is set:
- `X-Forwarded-For`
- `X-Forwarded-Host`
- `X-Forwarded-Server`
-The original `SERVER_NAME` can be sent to the proxied host by setting the [`ProxyPreserveHost`](https://httpd.apache.org/docs/2.4/mod/mod_proxy.html#ProxyPreserveHost) directive to `On`.
-```apache
-<VirtualHost *:80>
-    ServerName shaarli.domain.tld

-A brief guide on getting starting using docker is given in [Docker 101](docker-101.md).
-To learn more about user data and how to keep it across versions, please see [Upgrade and Migration](../Upgrade-and-migration.md).
-## Get and run a Shaarli image
-### DockerHub repository
-The images can be found in the [`shaarli/shaarli`](https://hub.docker.com/r/shaarli/shaarli/)
-repository.
-### Available image tags
- `latest`: latest branch
- `master`: master branch
- `stable`: stable branch
-The `latest`, `master` and `stable` images rely on:
- [Alpine Linux](https://www.alpinelinux.org/)
- [PHP7-FPM](http://php-fpm.org/)
- [Nginx](http://nginx.org/)
-Additional Dockerfiles are provided for the `arm32v7` platform, relying on
-[Linuxserver.io Alpine armhf
-images](https://hub.docker.com/r/lsiobase/alpine.armhf/). These images must be
-built using [`docker
-build`](https://docs.docker.com/engine/reference/commandline/build/) on an
-`arm32v7` machine or using an emulator such as
-[qemu](https://resin.io/blog/building-arm-containers-on-any-x86-machine-even-dockerhub/).
-### Download from Docker Hub

-```
-### Automatic builds
-Docker users can start a personal instance from an
-[autobuild image](https://hub.docker.com/r/shaarli/shaarli/).
-For example to start a temporary Shaarli at ``localhost:8000``, and keep session
-data (config, storage):
-```shell
-MY_SHAARLI_VOLUME=$(cd /path/to/shaarli/data/ && pwd -P)
-docker run -ti --rm \
-         -p 8000:80 \
-         -v $MY_SHAARLI_VOLUME:/var/www/shaarli/data \
-         shaarli/shaarli
-```
-### Volumes and data persistence
-Data can be persisted by [using volumes](https://docs.docker.com/storage/volumes/).
-Volumes allow to keep your data when renewing and/or updating container images:
-```shell
-# Create data volumes
-$ docker volume create shaarli-data
-$ docker volume create shaarli-cache
-# Create and start a Shaarli container using these volumes to persist data
-$ docker create \
-    --name shaarli \
-    -v shaarli-cache:/var/www/shaarli/cache \
-    -v shaarli-data:/var/www/shaarli/data \
-    -p 8000:80 \
-    shaarli/shaarli:master
-$ docker start shaarli
-```

-## Backup and restore the datastore file
-Backup the file `data/datastore.php` (by FTP or SSH). Restore by putting the file back in place.
-Example command:
-```bash
-rsync -avzP my.server.com:/var/www/shaarli/data/datastore.php datastore-$(date +%Y-%m-%d_%H%M).php
-```
-## Export links as...
-To export links as an HTML file, under _Tools > Export_, choose:
- _Export all_ to export both public and private links
- _Export public_ to export public links only
- _Export private_ to export private links only
-Restore by using the `Import` feature.
- This can be done using the [shaarchiver](https://github.com/nodiscc/shaarchiver) tool.
-Example command: 
-```bash
-./export-bookmarks.py --url=https://my.server.com/shaarli --username=myusername --password=mysupersecretpassword --download-dir=./ --type=all
-```
-## Import links from...
-### Diigo
-If you export your bookmark from Diigo, make sure you use the Delicious export, not the Netscape export. (Their Netscape export is broken, and they don't seem to be interested in fixing it.)
-### Mister Wong
-See [this issue](https://github.com/sebsauvage/Shaarli/issues/146) for import tweaks.
-### SemanticScuttle
-To correctly import the tags from a [SemanticScuttle](http://semanticscuttle.sourceforge.net/) HTML export, edit the HTML file before importing and replace all occurences of `tags=` (lowercase) to `TAGS=` (uppercase).
-### Scuttle
-Shaarli cannot import data directly from [Scuttle](https://github.com/scronide/scuttle).
-However, you can use the third-party [scuttle-to-shaarli](https://github.com/q2apro/scuttle-to-shaarli)
-tool to export the Scuttle database to the Netscape HTML format compatible with the Shaarli importer.
-### Refind
-You can use the third-party tool [Derefind](https://github.com/ShawnPConroy/Derefind) to convert refind.com bookmark exports to a format that can be imported into Shaarli.
-## Import Shaarli links to Firefox
- Export your Shaarli links as described above.
-    - For compatibility reasons, check `Prepend note permalinks with this Shaarli instance's URL (useful to import bookmarks in a web browser)`
- In Firefox, open the bookmark manager (not the sidebar! `Bookmarks menu > Show all bookmarks` or `Ctrl+Shift+B`)
- Select `Import and Backup > Import bookmarks in HTML format`
-Your bookmarks will be imported in Firefox, ready to use, with tags and descriptions retained. "Self" (notes) shaares will still point to the Shaarli instance you exported them from, but the note text can be viewed directly in the bookmark properties inside your browser. Depending on the number of bookmarks, the import can take some time.
-You may be interested in these Firefox addons to manage links imported from Shaarli
- [Bookmark Deduplicator](https://addons.mozilla.org/en-US/firefox/addon/bookmark-deduplicator/) - provides an easy way to deduplicate your bookmarks
- [TagSieve](https://addons.mozilla.org/en-US/firefox/addon/tagsieve/) - browse your bookmarks by their tags

-## Goals
- Getting a Virtual Private Server (VPS)
- Running Shaarli:
-    - as a Docker container,
-    - using the Træfik reverse proxy,
-    - securized with TLS certificates from Let's Encrypt.
-The following components and tools will be used:
- [Debian](https://www.debian.org/), a GNU/Linux distribution widely used in
-  server environments;
- [Docker](https://docs.docker.com/engine/docker-overview/), an open platform
-  for developing, shipping, and running applications;
- [Docker Compose](https://docs.docker.com/compose/), a tool for defining and
-  running multi-container Docker applications.
-More information can be found in the [Resources](#resources) section at the
-bottom of the guide.
-## Getting a Virtual Private Server
-For this guide, I went for the smallest VPS available from DigitalOcean,
-a Droplet with 1 CPU, 1 GiB RAM and 25 GiB SSD storage, which costs
-$5/month ($0.007/hour):
- [Droplets Overview](https://www.digitalocean.com/docs/droplets/overview/)
- [Pricing](https://www.digitalocean.com/pricing/)
- [How to Create a Droplet from the DigitalOcean Control Panel](https://www.digitalocean.com/docs/droplets/how-to/create/)
- [How to Add SSH Keys to Droplets](https://www.digitalocean.com/docs/droplets/how-to/add-ssh-keys/)
- [Initial Server Setup with Debian 8](https://www.digitalocean.com/community/tutorials/initial-server-setup-with-debian-8) (also applies to Debian 9)
- [An Introduction to Securing your Linux VPS](https://www.digitalocean.com/community/tutorials/an-introduction-to-securing-your-linux-vps)
-### Creating a Droplet
-Select `Debian 9` as the Droplet distribution:
-<img src="../images/01-create-droplet-distro.jpg"
-     width="500px"
-     alt="Droplet distribution" />
-Choose a region that is geographically close to you:
-<img src="../images/02-create-droplet-region.jpg"
-     width="500px"
-     alt="Droplet region" />
-Choose a Droplet size that corresponds to your usage and budget:
-<img src="../images/03-create-droplet-size.jpg"
-     width="500px"
-     alt="Droplet size" />
-Finalize the Droplet creation:
-<img src="../images/04-finalize.jpg"
-     width="500px"
-     alt="Droplet finalization" />
-Droplet information is displayed on the Control Panel:
-<img src="../images/05-droplet.jpg"
-     width="500px"
-     alt="Droplet summary" />
-Once your VPS has been created, you will receive an e-mail with connection
-instructions.
-## Obtaining a domain name
-After creating your VPS, it will be reachable using its IP address; some hosting
-providers also create a DNS record, e.g. `ns4853142.ip-01-47-127.eu`.
-A domain name (DNS record) is required to obtain a certificate and setup HTTPS
-(HTTP with TLS encryption).
-Domain names can be obtained from registrars through hosting providers such as
-[Gandi](https://www.gandi.net/en/domain).
-Once you have your own domain, you need to create a new DNS record that points
-to your VPS' IP address:
-<img src="../images/06-domain.jpg"
-     width="650px"
-     alt="Domain configuration" />
-## Host setup
-Now's the time to connect to your freshly created VPS!
-```shell
-$ ssh root@188.166.85.8

-root@stretch-shaarli-02:~$ chmod +x /usr/local/bin/docker-compose
-```
-## Running Shaarli
-Shaarli comes with a configuration file for Docker Compose, that will setup:
- a local Docker network
- a Docker [volume](https://docs.docker.com/storage/volumes/) to store Shaarli data
- a Docker [volume](https://docs.docker.com/storage/volumes/) to store Træfik TLS configuration and certificates
- a [Shaarli](https://hub.docker.com/r/shaarli/shaarli/) instance
- a [Træfik](https://hub.docker.com/_/traefik/) instance
-[Træfik](https://docs.traefik.io/) is a modern HTTP reverse proxy, with native
-support for Docker and [Let's Encrypt](https://letsencrypt.org/).
-### Compose configuration
-Create a new directory to store the configuration:
-```shell
-root@stretch-shaarli-02:~$ mkdir shaarli && cd shaarli
-root@stretch-shaarli-02:~/shaarli$
-```
-Download the current version of Shaarli's `docker-compose.yml`:
-```shell
-root@stretch-shaarli-02:~/shaarli$ curl -L https://raw.githubusercontent.com/shaarli/Shaarli/master/docker-compose.yml -o docker-compose.yml
-```
-Create the `.env` file and fill in your VPS and domain information (replace
-`<MY_SHAARLI_DOMAIN>` and `<MY_CONTACT_EMAIL>` with your actual information):
-```shell
-root@stretch-shaarli-02:~/shaarli$ vim .env
-```
-```shell
-SHAARLI_VIRTUAL_HOST=<MY_SHAARLI_DOMAIN>
-SHAARLI_LETSENCRYPT_EMAIL=<MY_CONTACT_EMAIL>

-### Decode datastore content
-To display the array representing the data saved in `data/datastore.php`, use the following snippet:
-```php
-$data = "tZNdb9MwFIb... <Commented content inside datastore.php>";
-$out = unserialize(gzinflate(base64_decode($data)));
-echo "<pre>"; // Pretty printing is love, pretty printing is life
-print_r($out);
-echo "</pre>";
-exit;
-```
-This will output the internal representation of the datastore, "unobfuscated" (if this can really be considered obfuscation).
-Alternatively, you can transform to JSON format (and pretty-print if you have `jq` installed):
-```
-php -r 'print(json_encode(unserialize(gzinflate(base64_decode(preg_replace("!.*/\* (.+) \*/.*!", "$1", file_get_contents("data/datastore.php")))))));' | jq .
-```
