 Referencing your Service from Routing
 -------------------------------------
 
-Registering your controller as a service is great, but you also need to make sure
-that your routing references the service properly, so that Symfony knows to use it.
+Registering your controller as a service is the first step, but you also need to
+update your routing config to reference the service properly, so that Symfony
+knows to use it.
 
+Use the ``service_id::method_name`` syntax to refer to the controller method.
 If the service id is the fully-qualified class name (FQCN) of your controller,
-you're done! You can use the normal ``App\Controller\HelloController::index``
-syntax in your routing and it will find your service.
+as Symfony recommends, then you can use something like:
+``App\Controller\HelloController::index``:
