Note on Patches/Pull Requests

  • Fork the project.
  • Make your feature addition or bug fix.
  • Add tests for it. This is important so I 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 I can ignore when I pull
  • Send me a pull request. Bonus points for topic branches.
