-### Silex
-
-Slugify also provides a service provider to integrate into Silex.
-
-```php
-// For Silex version 1
-$app->register(new Cocur\Slugify\Bridge\Silex\SlugifyServiceProvider());
-```
-
-```php
-// For Silex version 2
-$app->register(new Cocur\Slugify\Bridge\Silex2\SlugifyServiceProvider());
-```
-
-You can use the `slugify` method in your controllers:
-
-```php
-$app->get('/', function () {
-    return $app['slugify']->slugify('welcome to the homepage');
-});
-```
-
-And if you use Silex in combination with Twig register the `SlugifyServiceProvider` after the `Silex\Provider\TwigServiceProvider` to add the Twig extension to your environment and use the `slugify` filter in your templates.
-
-```twig
-{{ 'welcome to the homepage'|slugify }}
-```
-
 ### Mustache.php
 
 We don't need an additional integration to use Slugify in [Mustache.php](https://github.com/bobthecow/mustache.php).
