After I pooped out the initial version of rdoc.info a week or two ago, Jeff and I were bullshitting about the kind of stuff we could add to it when he had a bit of an epiphany: “the place for documentation about GitHub projects is on GitHub”. Yes! Of course! Why didn’t we think of that before?
So we registered the “docs” user on GitHub and went about building an extension to rdoc.info based on the GitHub pages platform. As of now, when you enter a project on rdoc.info, it’ll build docs for them locally and also generate a GitHub-themed set and push them to the docs user account pages on GitHub. In fact, you never even have to visit rdoc.info if you don’t want to (although project documentation will continue to be available there). For an example, see Nunemaker’s HTTParty API Docs. Make sure to play with the methods and namespaces buttons in the header.
