Based on this blog.
This guide shows you how to setup emacs to render a README.md very similarly to how github will do it; except it also works offline. There are no dependencies that can't be easily installed via the package manager on ubuntu.
- Install emacs24, the markdown mode, and pandoc. You may need the packages
emacs,emacs-goodies-el, andpandoc. - Get a style sheet that resembles the github style from this gist and store it. I put it in
~/emacs.d/github-pandoc.css.
