+- After the server runs, received messages are handled by `Rabbit::EventHandler` subclasses in two possible ways:
+  a)  Subclasses are selected by following code(by default):
+      ```ruby
+        "rabbit/handler/#{group_id}/#{event}".camelize.constantize
+      ```
+  b) you can change default behaviour to your own logic by setting the `handler_resolver_callable` config option with a `Proc` that should return the handler class:
+      ```ruby
+        Rabbit.config.handler_resolver_callable = -> (group_id, event) { "recivers/#{group_id}/#{event}".camelize.constantize }
+      ```
 
   They use powerful `Tainbox` api to handle message data. Project_id also passed to them.
