My current configuration is based on this starter repo.
To start, install git and nix-flakes
# Use a shell with git
nix-shell -p git home-manager
# Should be 2.4+ for these features
nix --version
export NIX_CONFIG="experimental-features = nix-command flakes"
# Update flakes
nix flake update
# Update the hardware configuration
cp /etc/nixos/hardware-configuration.nix ./hosts/.../hardware-configuration.nix
# Apply system configurations for a default system
sudo nixos-rebuild switch --flake .
# Apply the home manager configurations system
home-manager switch -b backup --flake .Use the nix installer from Determinate Systems. It provides nice features like a transparent installation, sets up the volume for the nix, has an easy uninstall script, etc.
