Functions
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 I can ignore when I pull)
-
Send me a pull request. Bonus points for topic branches.
