+The Admin interface is bundled within the SilverStripe Framework but is most commonly used in conjunction with the `cms`
 module. The main class for displaying the interface is a specialized [api:Controller] called [api:LeftAndMain], named
 as it is designed around a left hand navigation and a main edit form.
 
+Starting with SilverStripe 4, the user interface logic is transitioned from
+jQuery and [jQuery.entwine](https://github.com/hafriedlander/jquery.entwine),
+which is replaced with [ReactJS](http://reactjs.com/). The transition is
+done iteratively, starting with `AssetAdmin` and `CampaignAdmin`.
