 Translating Routes
 ------------------
 
-Symfony doesn't support defining routes with different contents depending on the
-user language. In those cases, you can define multiple routes per controller,
-one for each supported language; or use any of the bundles created by the
-community to implement this feature, such as `JMSI18nRoutingBundle`_ and
+Symfony support for internationalized routes depending on the user locale.
+
+For YAML configuration you can define an array in the `path` option to add 
+a different path per locale:
+
+.. code-block:: yaml
+
+    contact:
+        controller: App\Controller\ContactController::send
+        path:
+            en: /send-us-an-email
+            nl: /stuur-ons-een-email
+
+This option is available as well for XML and annotations:
+
+.. code-block:: php-annotations
+
+    use Symfony\Component\Routing\Annotation\Route;
+
+    class ContactController
+    {
+        /**
+         * @Route({
+         *     "en": "/send-us-an-email",
+         *     "nl": "/stuur-ons-een-email"
+         * }, name="contact")
+         */
+        public function send()
+        {
+            // ...
+        }
+    }
+
+For more advanced needs you can look on community bundles such as `JMSI18nRoutingBundle`_ and
 `BeSimpleI18nRoutingBundle`_.
