This is an upgrade to P2PU's 'Course in a Box'. The project uses GitHub Pages to allow you to quickly create and host your online course. You create an account in GitHub, clone their repository, and then make some edits to get your course up and running. Edit the course content collaboratively in GitHub, and you can also use Jekyll (a static site generation tool that converts markdown into full HTML (think of it in the same category as WebPack and Gulp)) to modify the look and feel of the course. This week P2PU announced they've "refurbished" Course-in-a-Box: "we've overhauled the site, simplified the tech, and vastly improved the getting-started documentation."
