 If you used custom commands before version 2.0, you need to update them. In most case you can just remove everything
 after the command name.

 ## Usage
 
 Build or rebuild the supervisor and worker configuration and start the daemon:
 ```sh
-$ app/console rabbitmq-supervisor:rebuild
+$ console rabbitmq-supervisor:rebuild
 ```
 
 Control the supervisord daemon:
 ```sh
-$ app/console rabbitmq-supervisor:control stop
-$ app/console rabbitmq-supervisor:control start
-$ app/console rabbitmq-supervisor:control restart
-$ app/console rabbitmq-supervisor:control hup
+$ console rabbitmq-supervisor:control stop
+$ console rabbitmq-supervisor:control start
+$ console rabbitmq-supervisor:control restart
+$ console rabbitmq-supervisor:control hup
 ```
