Please feel free to contribute. I welcome any help that you may offer. Whether it’s fixing typo’s, updating the documentation, or fixing bugs or adding new features.
If you wish to work on git-auto-commit-mode you can get the sources by cloning the repository:
git clone git://ryuslash.org/emacs/git-auto-commit-mode.org
Use spaces, don’t use tabs. If you can, keep lines shorter than 80 characters. Other than that, Emacs can handle indentation pretty well.
If you want to send any patches I’d be more than happy to merge them. Please feel free to use Github pull requests, or any other means preferred by you.
