-Register the Lazy-Loaded Extension as a Service
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Finally, register your new class as a service and tag it with ``twig.runtime``
-(and optionally inject any service needed by the Twig extension runtime):
-
-.. configuration-block::
-
-    .. code-block:: yaml
-
-        # app/config/services.yml
-        services:
-            app.twig_runtime:
-                class: AppBundle\Twig\AppRuntime
-                public: false
-                tags:
-                    - { name: twig.runtime }
-
-    .. code-block:: xml
-
-        <!-- app/config/services.xml -->

-                </service>
-            </services>
-        </container>
-
-    .. code-block:: php
-
-        // app/config/services.php
-        use AppBundle\Twig\AppExtension;
-
-        $container
-            ->register('app.twig_runtime', AppRuntime::class)
-            ->setPublic(false)

+If you're using the default ``services.yaml`` configuration, this will already
+work! Otherwise, :ref:`create a service <service-container-creating-service>`
+for this class and :doc:`tag your service </service_container/tags>` with ``twig.runtime``.
