To get started with Android for ARMv6/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/MSM7225/android.git -b ics

Then to sync up:

repo sync
sh vendor/cm/get-prebuilts
