+## Steps for a new droplet on DigitalOcean
+
+Start by creating a droplet using Debian. Create a new host configuration.
+
+Once the droplet is provisioned, we can use `nixos-anywhere` to convert the droplet to a NixOS installation.
+```sh
+nix run github:nix-community/nixos-anywhere -- --flake .#<host> --target-host root@<IP>
+```
+
+Once the host reboots, check that it's converted to NixOS by running `uname -a`.
