+6. The `provider` modules
+7. The `publisher` and `synchronizer` modules
+
+This is important to notice in order to avoid circular dependencies. For instance, if an `Extension` is declared with the `core` module as a dependency, RequireJS will inject `undefined` instead of the actual module.
+
+Any module though can access any dependencies by implementing the proper [injection listener][13] provided by the `eventMgr`.

 ### eventMgr
 
-The `eventMgr` module is responsible for receiving and dispatching events in **StackEdit**. The following functions of the `eventMgr` module will trigger events of the same name. Extensions can listen to these events by implementing functions with the same name. The function `addListener(eventName, callback)` of the `eventMgr` module can be used by any other module to listen to these events.
+The `eventMgr` module is responsible for receiving and dispatching events. Below is the list of all events signatures.
+
+Most events (those that are triggered outside the `eventMgr` module) can be triggered by calling methods of the same name in the `eventMgr` module. For example:
+
+```js
+eventMgr.onMessage('StackEdit is awesome!');
+```
+
+The method `addListener(eventName, callback)` of the `eventMgr` module can be used to listen to these events (except those that can only be handled by `Extension` objects). For example:
+
+```js
+eventMgr.addListener('onMessage', function(message) {
+    alert(message);
+});
+```
+
+`Extension` objects have the possibility to listen to those events by implementing methods of the same name. For example:
+
+```js
+userCustom.onMessage = function(message) {
+    alert(message);
+};
+```
