 You can of course also use normal :ref:`constructor injection <services-constructor-injection>`
 in your controllers.
 
-.. caution::
-
-    You can *only* pass *services* to your controller arguments in this way. It's not
-    possible, for example, to pass a service parameter as a controller argument,
-    even by using ``bind``. If you need a parameter, use the ``$this->getParameter('kernel.debug')``
-    shortcut or pass the value through your controller's ``__construct()`` method
-    and specify its value with ``bind``.

 For more information about services, see the :doc:`/service_container` article.
