#Shaarli configuration
## Foreword

**Do not edit configuration options in index.php! Your changes would be lost.** 

Once your Shaarli instance is installed, the file `data/config.php` is generated:
* it contains all settings, and can be edited to customize values
* it defines which [plugins](Plugin-System) are enabled[](.html)
* its values override those defined in `index.php`

## 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)

## Additional configuration

The playvideos plugin may require that you adapt your server's [Content Security Policy](https://github.com/shaarli/Shaarli/blob/master/plugins/playvideos/README.md#troubleshooting) configuration to work properly.[](.html)
