 Nix definitions to configure our physical servers.
 Currently, only one physical server (named jefke) is implemented.
 
-To deploy:
+## Deployment
-```
+
-nixos-rebuild switch -j auto --target-host root@jefke.hyp --flake ".#jefke"
+### Prerequisites
-```
+
+Before a NixOS definition can be deployed, some prerequite preparational steps must be performed.
+
+1. Manually install NixOS on the physical machine. This could potentially be automated in the future with [nixos-anywhere](https://github.com/nix-community/nixos-anywhere), but for now this is a manual process.
+2. Enable SSH and install authorized keys.
+3. Ensure Python3 is installed for Ansible.
+4. Run Ansible playbook which deploys secrets `ansible-playbook deploy_secrets.yml`.
+5. Deploy the NixOS definition: `nixos-rebuild switch -j auto --target-host root@jefke.hyp --flake ".#jefke"`.

-2. Configure SSH and install authorized keys
-3. Ensure python3 is present on the system
-4. Run Ansible script to copy secrets
-5. Run Nix to configure everything else
