The best way to get your changes merged back into core is as follows:
- Clone down your fork
- Create a thoughtfully named topic branch to contain your change
- Hack away
- Add tests and make sure everything still passes by running rake
- If you are adding new functionality, document it in the README
- Do not change the version number, I will do that on my end
- If necessary, rebase your commits into logical chunks, without errors
- Push the branch up to GitHub
- Send a pull request to the
