To get started with Pearl-OS, 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/PearlOS/platform_manifest.git -b pie
Then to sync up:
repo sync -c -f --force-sync --optimized-fetch --no-tags --no-clone-bundle --prune -j8
From root directory of Project, perform following commands in terminal
$ . build/envsetup.sh
$ lunch pearl_$device-userdebug
$ make zerotwo or brunch device
