Thanks for the interest in the Sandcastle Assist project.
With the exception of the HelpRegister project, all the other projects are still in their alpha stages of development,
and therefore not recommended for general uses (even though I use it extensively for my own work).
We are currently working hard to complete the various parts, but will recommend you take a look at the currently
