-Example with ``\RuntimeException`` and ``\Exception``:
+The order in which you configure exceptions is important because Symfony will
+use the configuration of the first exception that matches ``instanceof``:

             exceptions:

-                RuntimeException: # This will never be used as \RuntimeException extends \Exception
-                    log_level: debug
+                # The following configuration will never be used because \RuntimeException extends \Exception
