Send patches
For make a patch you need to branch the project, work on it, make local commits and when you think that you have your functionality done you can send us your contribution.
One simple way is to create a git branch:
git checkout -b mychanges ... work ... ... commit ... ... work ... ... commit ...
And when you think that it's ready for merge just publish your branch and send a request of merge. You can use gitorious for that or sending an email to development mailing list.
If you don't want to create a branch and publish that, you can send a patch using format-patch
