+    ));
+

+    public function registerBundles()
+    {
+        return array(
+            // ...

+        );
+    }
+
+Import the routing definition in `routing.yml`:
+

+    NelmioApiDocBundle:
+        resource: "@NelmioApiDocBundle/Resources/config/routing.yml"
+        prefix:   /
+
+Enable the bundle's configuration in `app/config/config.yml`:

+    nelmio_api_doc: ~
+
+
+## Usage ##
+
+### ApiDoc() annotation ###
+
+The bundle provides an `ApiDoc()` annotation for your controllers:
+
+``` php
+<?php
+
+namespace Your\Namespace;
+
+class YourController extends Controller
+{
+    /**
+     * @ApiDoc(
+     *  resource="true",
+     *  description="This is a description of your API method",
+     *  filters={
+     *      {"name"="a-filter", "dataType"="integer"},
+     *      {"name"="another-filter", "dataType"="string", "pattern"="(foo|bar) ASC|DESC"}
+     *  }
+     * )
+     */
+    public function getAction()
+    {
+    }
+
+    /**
+     * @ApiDoc(
+     *  description="Create a new Object",
+     *  formType="Your\Namespace\Form\Type\YourType"
+     * )
+     */
+    public function postAction()
+    {
+    }
+}
+```
+
+The following parameters are recognized:
+
+* `resource`: whether the method describes a resource or not;
+
+* `description`: a description of the API method;
+
+* `filters`: an array of filters;
+
+* `formType`: the Form Type associated to the method, useful for POST|PUT methods.
+
+Each _filter_ has to define a `name` parameter, but other parameters are free.
+
+If you set a `formType`, then the bundle automatically extracts parameters based on the given type,
+and determines for each parameter its data type, and if it's required or not.
+
+
