You must be running a 64-bit Linux distribution and must have installed some packages to build Nyanpasu. Google recommends using Ubuntu for this and provides instructions for setting up the system (with Ubuntu-specific commands) on the Android Open Source Project website.
Once you have set up your machine according to the instructions by Google, return here and carry on with the rest of the instructions.
To initialize, use a command like this:
repo init -u https://github.com/Project-Nyanpasu/manifest.git -b timobaka
Then to sync up:
repo sync
Use command to build Nyanpasu.
. build/envsetup.sh
lunch nyanpasu_{device}-{type}
mka bacon
Then enjoy it.
Currently we're using Gerrit as our code review platform.
