+## Realtime
+
+When [initializing](#initialize) RSMQ you can enable the realtime PUBLISH for new messages. On every new message that gets sent to RSQM via `sendMessage` a Redis PUBLISH will be issued to `{{rsmq.ns}:rt:{qname}.
+
+Example for RSMQ with default settings:
+
+* The queue `testQueue` already contains 5 messages.
+* A new message is being sent to the queue `testQueue`.
+* The following Redis command will be issued: `PUBLISH rsmq:rt:testQueue 6`
+
+### How to use the realtime option
+
+Besides the PUBLISH when a new message is sent to RSMQ nothing else will happen. Your app could use the Redis SUBSCRIBE command to be notified of new messages and issue a `receiveMessage` then. However make sure not to listen with multiple workers for new messages with SUBSCRIBE to prevent multiple simultaneous `receiveMessage` calls.
