 ### Observer Pattern as an External Service
 
 ##### About
-Below is an example taken from https://github.com/greglbd/angular-observer-pattern. This is an angular factory which reflects the Observer Pattern.  It works well with the ControllerAs method of working as it can be much more efficient that $scope.$watch and more specific to a unique scope or object than $emit and $broadcast when used correctly. 
 
-**Use Case:** You would use this pattern to communicate between 2 controllers that use the same model but are not connected in anyway
+Below is an example taken from [here](https://github.com/greglbd/angular-observer-pattern). This is an angular factory which creates a service implementing the Observer Pattern.  It works well with the ControllerAs method of working as it can be much more efficient that `$scope.$watch` and more specific to a unique scope or object than $emit and $broadcast when used correctly.
 
-##### Methods
-
-function adds a listener to an event with a callback which is stored against the event with it's corresponding id.
-```
-_observerService.attach = function(callback, event, id)
-```
-
-
-function removes all occurences of one id from all events in the observer object
-```
-_observerService.detachById = function(id)
-```
+**Use Case:** You would use this pattern to communicate between 2 controllers that use the same model but are not connected in anyway.
 
+##### Controller Example
 
-function removes all occurences of the event from the observer Object
-```
-_observerService.detachByEvent = function(event)
-``` 
+Below example shows how to attach, notify and detach an event.
 
+```javascript
+angular.module('app.controllers')
+  .controller('ObserverExample', ObserverExample);
+ObserverExample.$inject= ['ObserverService', '$timeout'];
 
-removes all callbacks for an id in a specific event from the observer object
-```
-_observerService.detachByEventAndId = function(event, id)
-```
+function ObserverExample(ObserverService, $timeout) {
+  var vm = this;
+  var id = 'vm1';
 
+  ObserverService.attach(callbackFunction, 'let_me_know', id)
 
-Notifies all observers of a specific event, can pass a params variable of any type
-```
-_observerService.notify = function(event, parameters)
-```
-
+  function callbackFunction(params){
+    console.log('now i know');
+    ObserverService.detachByEvent('let_me_know')
+  }
 
-##### Controller Example
-Below example shows how to attach, notify and detach an event.
-```javascript
-angular.module('app.controllers')
-  .controller('ObserverExample',ObserverExample);
-ObserverExample.$inject= ['ObserverService','$timeout'];
-function ObserverExample(ObserverService, $timeout) {
-    var vm = this;
-    var id = 'vm1';
-    ObserverService.attach(callbackFunction, 'let_me_know', id)
-    
-    function callbackFunction(params){
-        console.log('now i know');
-        ObserverService.detachByEvent('let_me_know')
-    }
-    
-    $timeout(function(){
-        ObserverService.notify('let_me_know');
-    },5000);
+  $timeout(function(){
+    ObserverService.notify('let_me_know');
+  }, 5000);
 }
 ```
 Alternative way to remove event
 
 ```javascript
 angular.module('app.controllers')
-  .controller('ObserverExample',ObserverExample);
-ObserverExample.$inject= ['ObserverService','$timeout', '$scope'];
+  .controller('ObserverExample', ObserverExample);
+ObserverExample.$inject= ['ObserverService', '$timeout', '$scope'];
+
 function ObserverExample(ObserverService, $timeout, $scope) {
-    var vm = this;
-    var id = 'vm1';
-    ObserverService.attach(callbackFunction, 'let_me_know', id)
-    
-    function callbackFunction(params){
-        console.log('now i know');
-    }
-    
-    $timeout(function(){
-        ObserverService.notify('let_me_know');
-    },5000);
-    
-    // Cleanup listeners when this controller is destroyed
-    $scope.$on('$destroy', function handler() {
-        ObserverService.detachByEvent('let_me_know')
-    });
+  var vm = this;
+  var id = 'vm1';
+  ObserverService.attach(callbackFunction, 'let_me_know', id)
+
+  function callbackFunction(params){
+    console.log('now i know');
+  }
+
+  $timeout(function(){
+    ObserverService.notify('let_me_know');
+  }, 5000);
+
+  // Cleanup listeners when this controller is destroyed
+  $scope.$on('$destroy', function handler() {
+    ObserverService.detachByEvent('let_me_know')
+  });
 }
