Start by downloading the repository as a .zip using the green "Clone or download" on the top right.
Extract the zipped contents. Open a terminal and navigate into the LinuxSetup folder.
Set setup.sh as executable with the command:
chmod +x setup.sh
Then to run the script, use the command:
sudo ./setup.sh
The script will have a few prompts at the beginning, and then at the end. It will finally prompt to reboot, which I recommend.
