Patches are always welcome! I'm fine with Pull Requests. However this build isn't supported by CM and you should work on the official CM Tree.
To get started with Android/CyanogenMod, you'll need to get familiar with Git and Repo.
To initialize your local repository using the CyanogenMod trees, use a command like this:
repo init -u git://github.com/vork/android.git -b jellybean
Then to sync up:
repo sync
Please see the CyanogenMod Wiki for building instructions.
