+### Declaring Queues and Exchanges
+
+Since v3.0, all queues and exchanges are by default declared on demand using the console command: 
+
+```
+php index.php rabbitmq:declareQueuesAndExchanges
+```
 
-Note: Queue will be created automatically after publishing first message. 
+It's intended to be a part of the deploy process to make sure all the queues and exchanges are prepared for use.
+
+If you need to override this behavior (for example only declare queues that are used during a request and nothing else), 
+just add the `autoCreate: true` parameter to queue or exchange of your choice.
+
+You may also want to declare the queues and exchanges via rabbitmq management interface or a script but if you fail to 
+do so, don't run the declare console command and don't specify `autoCreate: true`, exceptions will be thrown 
+when accessing undeclared queues/exchanges.
