To get started with Project Flare, you'll need to get familiar with Source Control Tools.
To initialize your local repository, use a command like this:
repo init -u https://github.com/Project-Flare-Staging/android.git -b sixteen --git-lfs
Then to sync up:
repo sync -c -j$(nproc --all) --force-sync --no-clone-bundle --no-tags
From root directory of Project, perform following commands in terminal
$ . build/envsetup.sh
$ lunch flare_$device-bp2a-user
$ make bacon
