To get started with EFIDroid, you'll need to get familiar with Git and Repo.
To initialize your local repository using the EFIDroid trees, use a command like this:
repo init -u https://github.com/efidroid/manifest.git -b master
Then to sync up:
repo sync
Please see the EFIDroid Wiki for building instructions.
This can be useful if you want to work on additional EFIDroid projects.
mkdir -p .repo/local_manifests
ln -s ../manifests/optional.xml .repo/local_manifests/optional.xml
