Note
You should review the configuration variables in flake.nix before installing. Also take a look at the branches, the difference between them resides in nvidia drivers
Remember to add this nix.settings.experimental-features = ["flakes nix-command"]; to enable nix-command and flakes in /etc/nixos/configuration.nix and then
sudo nixos-rebuild switch
nixpkgs#git clone https://github.com/Acosta-JJ/NixOS.git ~/NixOS
cd ~/NixOS
./install.sh
