This package provides a theme for Emacs, inspired by the GitHub website user interface. It attempts to stay true to the GitHub syntax highlighting colors, while still looking good in every language inside Emacs.
GitHub Theme is available in MELPA.
You can install it with the following command:
M-x package-install github-theme
To load it automatically on Emacs startup, add this to your initialization file:
(load-theme 'github t)
