-  0) Fork this repo, and write your own host config at `hosts/nixos/<YOUR_CONFIG_NAME>/default.nix` (you can use one of the other configurations as a template. Also see https://github.com/Swarsel/.dotfiles/tree/main/modules for a list of all additional options). At the very least, you should replace the `secrets/` directory with your own secrets and replace the SSH public keys with your own ones (otherwise I will come visit you!🔓❤️). I personally recommend to use the literate configuration and `org-babel-tangle-file` in Emacs, but you can also simply edit the separate `.nix` files.

   1) Have a system with `nix` available booted (this does not need to be installed, i.e. you can use a NixOS installer image; a custom minimal installer ISO can be built by running `just iso` in the root of this repo)
   2) Make sure that your Yubikey is plugged in or that you have your SSH key available (and configured)
   3) Run `swarsel-bootstrap -n <CONFIGURATION_NAME> -d <TARGET_IP>` on your existing system.

     1) Have a system with `nix` available booted (this does not need to be installed, i.e. you can use a NixOS installer image; a custom minimal installer ISO can be built by running `just iso` in the root of this repo)
     2) Make sure that your Yubikey is plugged in or that you have your SSH key available (and configured)
     3) Run `swarsel-bootstrap -n <CONFIGURATION_NAME> -d <TARGET_IP>` on your existing system.
