 ## Note on Patches/Pull Requests
 
 * Fork the project.
 * Make your feature addition or bug fix.
 * Add tests for it. This is important so we don't break it in a future version unintentionally.
 * Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine, but bump version in a commit by itself so we can ignore when we pull)
-* Send us a pull request. Bonus points for topic branches.
