The ASP.NET Atlas team have just released an "Atlas Wiki Sample Kit" based on the current Atlas build. This Wiki comes as a .VSI file that installs an "Atlas Wiki" template into your list of templates for Visual Studio 2005 (currently C# only).
Currently it requires that Visual Studio 2005 or Web Developer Express be installed on your machine. It demonstrates some of the features within Atlas and comes with source code so you can see how its all done. Note that its currently a preview only and you cannot "go live" with this release (this is all stated in the boring licence spiel) however feedback on this is welcome and a go live licence will accompany a future Wiki sample kit release (date is currently unknown).
