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/tandob-mtk/android-mtk.git -b cm-13.0-mt6592
repo sync -f --force-sync --no-clone-bundle
source build/envsetup.sh
