GitHub open sourced this long-lived private project. Learn about the why and how in this post…

Last week we open sourced all of GitHub’s product documentation, along with the Node.js web application that powers it. Check out our new public repository at github.com/github/docs.

This post tells the story of why we wanted to open source the docs, what tools we built and open sourced along the way, and how we worked to make the project welcoming to external contributors.
