 The directive will create a method on `$scope.CallMe` so that you can invoke it yourself later.  Make sure the there isn't a method `CallMe` already in your controller. To use the method be sure to wrap it with `$timeout`. You don't have to use `CallMe`, you can specify some other name.

 You can start the intro from code, either call `$scope.CallMe();`.  If the `$scope.CallMe();` doesn't work, it might be because your DOM isn't ready. Put it in a `$timeout`.
 
 ### Autostart

 ### Autorefresh
 
 If an intro tour includes dynamic content, use `ng-intro-autorefresh="true"` to call Intro.js' refresh method.
 
 ### Callbacks
 
-Intro.js provides several callbacks.  You can receive these callbacks in your controller.  For example, for the `onchange` event, specify the function name in the directive.
