-## Adding event manager awareness to your classes
+### Subscribers
 
-**CAUTION**: This make use of the singleton instance of event manager.
-Singletons are usually a bad idea, so prefer dependency injection over
-singleton instances.
+You can add and remove subscribers as follows:
 
 ```ruby
-require "koine/event_manager/event_manager_aware"
-
-class MyModel
-  include Koine::EventManager::EventManagerAware
-
-  def some_method
-    event_manager.trigger(SomeEvent.new(foo: :bar))
+class MySubscriber
+  def publish(event)
+    # do something
   end
 end
-```
 
-The above is the same as:
+subscriber = MySubscriber.new
 
-```ruby
-class MyModel
-  def some_method
-    event_manager.trigger(SomeEvent.new(foo: :bar))
-  end
-
-  def event_manager
-    Koine::EventManager::EventManager.instance
-  end
-end
+event_manager.subscribe(subscriber, to: UserListener)
+event_manager.unsubscribe(subscriber, from: UserListener)
 ```
