This page uses github.js to retrieve the Markdown from Github, edit it via Bootstrap Markdown Editor and push to GitHub again with github.js. To save you need to enter the password (HTTP Basic Authentication) for the repository…
The API queries are limited to somehow 60 requests/hour for unautorized requests, e.g. to receive the source code of this page.
API rate limit exceeded for your IP. (But here’s the good news: Authenticated requests get a higher rate limit. Check out the documentation for more details.)
To enable the edit function you need to append ?edit=true to the address of the post.
