Use DocPad, GitHub and Prose as a Wiki
This guide will walk you through how you can use a GitHub repository to house your wiki content, have DocPad render it, and automatically update on changes. It's also really nice as we get to benefit from the github project workflow for our wiki, that is issues, pull requests, etc.
We use this workflow heavily by linking the DocPad Website and the DocPad Documentation repositories allowing us to have users edit and submit pull requests for improvements to our documentation, and once merged, the website regenerates automatically.
