+# Example nixos system deployment
+
+This is an example of how to deploy a full nixos system with a separate user unit to a bare machine.
+
+1. Run bare system from `.#nixosConfigurations.bare`
+  - `nix build .#nixosConfigurations.bare.config.system.build.vm`
+  - `QEMU_NET_OPTS=hostfwd=tcp::2221-:22 ./result/bin/run-bare-system-vm`
+2. `nix run github:serokell/deploy --prime`
+3. ???
+4. PROFIT!!!
