+Using a custom route repository with Dynmaic Router
+===================================================
+
+The Dynamic Router allows you to customize the route Repository (i.e. the class 
+responsible for retrieving routes from the database), and by extension, the 
+Route objects.
+
+Creating the route repository
+-----------------------------
+
+The route repository must implement the `RouteRepositoryInterface` The 
+following class provides a simple solution using an ODM Repository.
+
+.. code-block:: php
+
+    <?php
+
+    namespace MyVendor\Bundle\MyBundle\Repository;
+    use Doctrine\ODM\PHPCR\DocumentRepository;
+    use Symfony\Cmf\Component\Routing\RouteRepositoryInterface;
+    use Symfony\Component\Routing\RouteCollection;
+    use Symfony\Component\Routing\Route as SymfonyRoute;
+
+    class RouteRepository extends DocumentRepository implements RouteRepositoryInterface
+
+    {
+        // this method is used to find routes matching the given URL
+        public function findManyByUrl($url)
+        {
+            // for simplicity we retrieve one route
+            $myDocument = $this->findOneBy(array(
+                'url' => $url,
+            ));
+
+            $pattern = $myDocument->getUrl(); // e.g. "/this/is/a/url"
+
+            $collection = new RouteCollection();
+
+            // create a new Route and set our document as
+            // a default (so that we can retrieve it from the request)
+            $route = new SymfonyRoute($ep->getPath(), array(
+                'document' => $document,
+            ));
+
+            // add the route to the RouteCollection using
+            // a unique ID as the key.
+            $collection->add('my_route_'.uniqid(), $route);
+
+            return $collection;
+        }
+
+        // this method is used to generate URLs, e.g. {{ path('foobar') }}
+        public function getRouteByName($name, $params = array())
+        {
+            $document = $this->findOneBy(array(
+                'name' => $name,
+            ));
+
+            if ($route) {
+                $route = new SymfonyRoute($route->getPattern(), array(
+                    'document' => $document,
+                ));
+            }
+
+            return $route;
+        }
+    }
+
+.. tip::
+
+    As you may have noticed we return a `RouteCollection` object - why not return 
+    a single `Route`? The Dynamic Router allows us to return many *candidate* routes,
+    in other words, routes that *might* match the incoming URL. This is important to
+    enable the possibility of matching *dynamic* routes, `/page/{page_id}/edit` for example.
+    In our example we match the given URL exactly and only ever return a single `Route`.
+
+Replacing the default CMF repository
+------------------------------------
+
+To replace the default `RouteRepository` it is necessary to modify your configuration
+as follows:
+
+.. configuration-block::
+
+   .. code-block:: yaml
+
+       # app/config/config.yml
+       symfony_cmf_routing_extra:
+           dynamic:
+               enabled: true
+               route_repository_service_id: my_bundle.repository.endpoint
+   
+Where `my_bundle.repository.endpoint` is the service ID of your repository. 
+See `Creating and configuring services in the container <http://symfony.com/doc/current/book/service_container.html#creating-configuring-services-in-the-container/>`_ 
+for information on creating custom services.
