The tutorial is divided into two sections: the first shows how you can use QuickUI controls in your site (e.g., one mostly constructed via some other tool), and the second shows how to create your own QuickUI controls. The tutorial is built around small interactive coding exercises, each of which demonstrates some aspect of the framework. Due to current limitations of the code editor, the tutorial is not functional in IE8 and Safari. It works fine in Chrome, Firefox, and IE9.
The existing markup tutorial has been moved to a new Markup section that also now hosts the Downloads page for the client-side compiler. This reorganization helps emphasize the fact that the use of QuickUI markup is an optional, somewhat advanced mode of use; markup is no longer required to use or create QuickUI controls.
