There are a few products that will convert the generated visual studio XML comments file into something more human friendly.
My favourite is "Sandcastle Help File Builder"
This is the getting started page:
Sandcastle projects are compiled by MSBuild so you can integrate them in your solution very easily. You can configure the output to be an MSDN style CHM file or if you prefer a HTML page or even a PDF...
It's a really cool product. And it's free!
PS: Have you looked at GhostDoc for your XML comments?
