Purple Pi is a browser extension for Google Chrome that renders LaTeX-style mathematics on pages that don't otherwise support it. Examples are GitHub READMEs, GitHub Wikis, and StackOverflow posts.
On GitHub pages, just use ```math code blocks or $`...`$ inlines. See https://github.com/nschloe/purple-pi for more info.
