 ## MonitoringStore
 This store emits the events that are necessary to emit notifications when resources change.
 
+There are 4 different events that can be emitted:
+- `this.emit('changed', identifier, AS.Create | AS.Update | AS.Delete | undefined)`: is emitted for every resource that was changed/effected by a call to the store.
+- `this.emit(AS.Create, identifier)`: is emitted for every resource that was created by the call to the store.
+- `this.emit(AS.Update, identifier)`: is emitted for every resource that was updated by the call to the store.
+- `this.emit(AS.Delete, identifier)`: is emitted for every resource that was deleted by the call to the store.
+
+A `changed` event will always be emitted if a resource was changed.
+If the correct metadata was set by the source `ResourceStore`, an additional field will be sent along indicating the type of change,
+and an additional corresponding event will be emitted, depending on what the change is.
+
 ## IndexRepresentationStore
 When doing a GET request on a container `/container/`,
 this container returns the contents of `/container/index.html` instead if HTML is the preferred response type.
