Picar-x Installation problem

cd /home/pi/
git clone -b v2.0 GitHub - sunfounder/picar-x
cd picar-x
sudo python3 setup.py install

After all these manipulations, setup.py file not found. On git hub offered to use file xxx.py, but it also isn’t in this repo. What do you think I should do?

Thank you for answers!

You seem to have cloned the wrong branch, Install All the Modules(Important) — SunFounder PiCar-X Kit documentation please clone the v2.0 branch, delete the file and clone again:
cd ~
sudo rm - r picar-x
git clone -b v2.0 GitHub - sunfounder/picar-x
cd ~/picar-x
sudo python3 setup.py install
