Because you want to use Emoji everywhere, like me. Because you love TextExpander and are always looking for more snippets...
Clone the repo to download. Or curl. Or whatever you feel most comfortable with.
Snippets follow conventions found at Emoji Cheat Sheet: they should match one-for-one with Github emoji (in most cases). For example, :smiley: or :poop:.
