- `config.inc.php`: optional. Included by the `modules/School_Setup/includes/Plugins.inc.php` file when the _Configuration_ link in the plugin listing is clicked.
## Example
You can base your work or reuse any existing plugin. The list of available plugins can be found at https://www.rosariosis.org/add-ons/
## Action hooks
You typically want to register your functions to be hooked on certain actions. The list of actions is available in the [`functions/Actions.php`](https://gitlab.com/francoisjacquet/rosariosis/blob/mobile/functions/Actions.php) file.
For example, to load a specific JS or CSS file in the HTML `` use this code:
```php
// Add our MyPluginHeadLoadJSCSS() function to the Warehouse.php|header_head action.
add_action( 'Warehouse.php|header_head', 'MyPluginHeadLoadJSCSS' );
/**
* Load JS and CSS in HTML head
* Load mystylesheet.css & myjavascriptfile.js files.
*
* @uses Warehouse.php|header_head action hook
*/
function MyPluginHeadLoadJSCSS()
{
echo '';
echo '';
}
```
