To initialize your local repository, use a command like this:
repo init -u https://github.com/one-wip/manifest -b pie
or to save bandwith and space
repo init -u https://github.com/one-wip/manifest -b pie --depth=1
Then to sync up:
repo sync -c -f --force-sync --optimized-fetch --no-tags --no-clone-bundle --prune -j8
