## Foreword
**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[](.html)
* 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[](.html)
## Configuration

**trusted_proxies**: List of trusted IP which won't be banned after failed login attemps. Useful if Shaarli is behind a reverse proxy.
**allowed_protocols**: List of allowed protocols in shaare URLs or markdown-rendered descriptions. Useful if you want to store `javascript:` links (bookmarklets) in Shaarli (default: `["ftp", "ftps", "magnet"]`).
### Resources
**data_dir**: Data directory.
**datastore**: Shaarli's links database file path.
**history**: Shaarli's operation history file path.

### Privacy
**default_private_links**: Check the private checkbox by default for every new link.
**hide_public_links**: All links are hidden while logged out.
**hide_timestamps**: Timestamps are hidden.
### Feed
**rss_permalinks**: Enable this to redirect RSS links to Shaarli's permalinks instead of shaared URL.
**show_atom**: Display ATOM feed button.
### Thumbnail
**enable_thumbnails**: Enable or disable thumbnail display.
**enable_localcache**: Enable or disable local cache.
