When developing one of my project, I wanted to make a website with my GitHub project's wiki integrated into it.
This tool is made to serve a GitHub's Gollum wikis. The final goal is to support all components of Gollum RedCarpet markdown syntax.
You can define a header and a footer, so the wiki will look as a part of your website.
This won't support editing, that's what Gollum is made for. This is simply to provide a way of integrating your GitHub project's wiki into your existing website.
This module is at the beginning of its development, so please be patient!
