We love pull requests from everyone. When contributing, please consider to join us on IRC. We are on #AppImage on irc.freenode.net.
Fork, then clone the appimagetool/master branch of the repo:
git clone -b appimagetool/master --single-branch --recursive git@github.com:your-username/AppImageKit.git
Compile:
cd AppImageKit/
sudo bash -ex install-build-deps.sh
bash -ex build.sh
Make your change. Build again to be sure you didn't break anything. Run the resulting binaries to test them.
Push to your fork and submit a pull request.
At this point you're waiting on us. We like to at least comment on pull requests within three business days (and, typically, one business day). We may suggest some changes or improvements or alternatives.
