Also on this site is the Interactive SDK:
This Interactive SDK makes starting out with the Messenger Web Toolkit even easier for developers. To get to this, click on the Learn tab on the site. After signing in you can play around with it, the markup is shown in the bar and will update every time you change something. You can copy/paste this markup once you are satisfied with the result (per control). Need more info on the control? No problem, a MSDN link to the control is provided on the right.
If you want to give feedback on the Interactive SDK, you are welcome to do so on the forum.
