To get started with Keepod OS, you'll need to install [Git and Repo] (https://source.android.com/source/downloading.html) first.
To initialize your local repository using the Keepod OS code tree:
repo init -u git://github.com/Keepod/keepodos.git
Then to sync up:
repo sync
Then to build:
cd <source-dir>; . build/envsetup.sh; brunch android-x86
