-# Upgrading From 2.x To 3.0
-
-NelmioApiDocBundle has been entirely refactored in 3.0 to focus on Swagger
-and most of it has changed.
-
-## Upgrade Your Annotations
-
-The `@ApiDoc` annotation has been removed and you must now use
-[Swagger-php](https://github.com/zircote/swagger-php) annotations.
-
-An upgrade example:
-```php
-use Nelmio\ApiDocBundle\Annotation\ApiDoc;
-
-class YourController extends Controller
-{
-    /**
-     * This is a description of your API method.
-     *
-     * @ApiDoc(
-     *  filters={
-     *      {"name"="a-filter", "dataType"="integer"},
-     *      {"name"="another-filter", "dataType"="string", "pattern"="(foo|bar) ASC|DESC"}
-     *  }
-     * )
-     */
-    public function getAction()
-    {
-    }
-}
-```
-
-will become:
-```php
-use Swagger\Annotations as SWG;
-
-class YourController extends Controller
-{
-    /**
-     * This is a description of your API method.
-     *
-     * @SWG\Parameter(
-     *     name="a-filter",
-     *     in="query",
-     *     type="integer"
-     * )
-     * @SWG\Parameter(
-     *     name="another-filter",
-     *     in="query",
-     *     type="string",
-     *     format="(foo|bar) ASC|DESC"
-     * )
-     */
-    public function getAction()
-    {
-    }
-}
