My own NixOS configuration, made for myself so probably won't suit you well.

1. Clone the repo

git clone git@github.com:Superredstone/nixos.git ~/.nixos && cd .nixos

2. Choose an hostname
3. Copy your current configuration inside of machines/$HOSTNAME
4. Create a file named machines/$HOSTNAME/default.nix with the following contents

{ ... }: 
{
	imports = [
		./configuration.nix
	];
}

5. Follow secrets/README.md
6. Switch to the new configuration

HOSTNAME=HOSTNAME just switch
