 Rate Limiting in Action
 -----------------------
 
+Injecting the Rate Limiter Service
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

+After having configured one or more rate limiters, you have two ways of injecting
+them in any service or controller:
+
+**(1) Use a specific argument name**
+
+Type-hint your construtor/method argument with ``RateLimiterFactoryInterface`` and name
+the argument using this pattern: "rate limiter name in camelCase" + ``Limiter`` suffix.
+For example, to inject the ``anonymous_api`` limiter defined earlier, use an
+argument named ``$anonymousApiLimiter``::

+    // src/Controller/ApiController.php

+    use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;

+the ``#[Target]`` attribute helps you select which one to inject. Symfony creates
+a target called "rate limiter name" + ``.limiter`` suffix.
+
+For example, to select the ``anonymous_api`` limiter defined earlier, use
+``anonymous_api.limiter`` as the target::

+    // ...
