+   `git-game.spec` and commit your changes.

+   push git commits and tags, and push the `.gem` file to
+   [rubygems.org](https://rubygems.org).

-- Put it somewhere on your PATH (like /usr/local/bin)
+- `gem install git-game` (or perform [manual installation](#manual-installation)).
 - Then, in any git repository, run `git game`
 - (If you'd like, you can select a subset of commits, for example, `git game --after={2014-08-08}`. For more options, see [http://gitref.org/inspect/](http://gitref.org/inspect/).)
