+### How to deploy
+
+Via git, build on remote:
+
+  ssh -t HOST sudo nixos-rebuild test --flake git+ssh://git@github.com/pbsds/nix-dotfiles.git --recreate-lock-file --no-write-lock-file
+
+From local checkout to remote where you're not a trusted user, build on remote:
+
+  tar cf - --directory="$(nix eval --raw .#inputs.self.outPath)" . | ssh bolle.pbsds.net -- bash -xc '"cd $(mktemp -d); pwd; tar xf - && nixos-rebuild test . \"\$@\""' -- --recreate-lock-file --no-write-lock-file
+
+.. wait doesn't that litter `/tmp` or `/run/user/.../tmp`?
+
+  ¯\_(ツ)_/¯
+
+From local checkout to remote if local nix daemon has ssh keys, then build on remote:
+
+  nix copy --from "$(nix eval  .#inputs.self.outPath)" --to TODO
