+  * You're ready to use the Messenger component. You can define your own message buses
+    or start using the default one right now by injecting the <info>messenger.bus.default</info> service
+    or typehinting <info>Symfony\Component\Messenger\MessageBusInterface</info> in your code.
+
+  * To send messages to a transport and handle them asynchronously:
+
+    1. Uncomment the <comment>MESSENGER_TRANSPORT_DSN</> env var in .env
+       and <comment>framework.messenger.transports.async</> in config/packages/messenger.yaml;
+    2. Route your message classes to the async transport in config/packages/messenger.yaml.
