Install on a new machine. Pass the config name from the table below: the hostname is set by the config itself, so it is not yet known on the first run.

nix --extra-experimental-features 'nix-command flakes' run github:kannapoix/dotfiles -- <config name>

Apply. Each host config sets networking.hostName, so darwin-rebuild and home-manager pick the config for the current machine by hostname; no #name is needed after the first run.

sudo darwin-rebuild switch --flake ~/dotfiles

home-manager switch --flake ~/dotfiles
