To get started with Project Blaze, you'll need to get familiar with Repo and Version Control with Git.
To initialize your local repository, use a command like this:
repo init -u https://github.com/xAndroidGangx/manifest.git -b 13
Then to sync up:
repo sync -c -j$(nproc --all) --force-sync --optimized-fetch --no-tags --no-clone-bundle --prune
From root directory of Project, perform following commands in terminal
$ . build/envsetup.sh
$ lunch blaze_$device-userdebug
$ brunch <device_codename>
