% Plugins
Tiny Tiny RSS supports many kinds of plugins: social plugins which share articles to various sites,
article filter plugins which mangle feed-provided data on import (for example, inlining images or extracting
full article text using Readability), hotkey plugins which alter the way keyboard shortcuts work, etc.
There are two kinds of plugins: user and system. User plugins are enabled in ``Preferences -> Plugins``. System plugins require adding them to a config.php
directive PLUGINS
which is a comma-separated list of enabled system plugins, i.e.
```php
define('PLUGINS', 'updater, digest, auth_remote, auth_internal');
```
- system plugins are always enabled for all users
- if multiple search plugins are loaded, only the first one is used
If you are interested in making plugins, see [MakingPlugins](wiki/MakingPlugins) and [samples](https://git.tt-rss.org/git/tt-rss-samples) repositories for examples to get you started.
### Installing plugins
Copy plugin folder to ```tt-rss/plugins.local``` then activate it in the settings panel. Plugin folder name should correspond to plugin class name defined in ``(plugin)/init.php``, i.e. ``Af_ExamplePlugin`` should be copied to ``plugins.local/af_exampleplugin``.
