Downloading basic viewpoints to edit

I want to download the basic viewpoint for mass and then edit it, however I cannot find a way to do this. I found the project in the git tree online but dont understand how to extract the files.
Thank you in advance,

You can clone the gerrit repository by using this command: git clone
This repository host Basic Mass, Basic Price and Basic Performance.
