 RunMQ can leverage RabbitMQ policies to manage the delay between attempts, it's not used by default, however it's <b>highly recommended</b> to enable it. 
 
-- When `usePoliciesForDelay` is enabled, RunMQ creates delay queues with TTL configured via RabbitMQ policies rather than hard-coding TTL in the queue itself.
+- When `usePoliciesForDelay` is enabled in consumer config, RunMQ creates delay queues with TTL configured via RabbitMQ policies rather than hard-coding TTL in the queue itself.
 - Hard-coding the TTL requires manual queue re-declaration to change delays, which can involve deleting queues - making it cumbersome and error-prone.
 - Policies allow dynamic updates to the TTL without recreating queues — you can change attempts delay anytime, and RunMQ will take care of the rest.
