The project is out on GitHub and even has a NuGet package so it can be easily used by web developers. Full documentation is currently in the README file on the GitHub page.
In the process of preparing FluentSiteMap for the OSS world, I also published two more projects, both used by FluentSiteMap:
- NUnitExtensions - Handy base test classes and other extensions useful for TDD using NUnit (also has a NuGet package)
- Buildage - The easy build and packager for C# projects (integrates into other projects using Git submodules)
