I've used [Wyam](https://wyam.io/) for some dotnet stuff and it works pretty well. Docs are written in markdown and it generates a static site with them. It can also generate api docs pages (with a search interface) from C# source files or compiled libs which was pretty cool IMHO.
Exactly. I worked at a place where the majority of dev teams had little to no automated tests. Getting them to write tests was near impossible due to it 'taking too much time away from features and bug fixes'.
One team adopted TDD and forced themselves to do it for a year. They admitted it slowed their overall dev-cycle down a ton, but they ended up learning a lot about how to build a well designed API. I think more internal documentation about good design emerged from that then them evangelizing TDD.
