 # nixos-servers
 
 Nix definitions to configure our physical servers.
-Currently, only one physical server (named jefke) is implemented.
+Currently, only one physical server (named jefke) is implemented but more are planned!
+
+## Prerequisites
+
+1. Install the Nix package manager or NixOS ([link](https://nixos.org/download))
+2. Enable flake and nix commands ([link](https://nixos.wiki/wiki/Flakes#Enable_flakes_permanently_in_NixOS))
+3. Install Direnv ([link](https://direnv.net/))
+4. Allow direnv for this repository: `direnv allow`
+
+## Bootstrapping
+
+We bootstrap our physical server using [nixos-anywhere](https://github.com/nix-community/nixos-anywhere).
+This reformats the hard disk of the server and installs a fresh NixOS.
+Additionally, it deploys an age identity, which is later used for decrypting secrets.
+
+⚠️  This will wipe your server completely ⚠️
+
+1. Make sure your have a [Secret service](https://www.gnu.org/software/emacs/manual/html_node/auth/Secret-Service-API.html) running (such as Keepassxc) that provides the age identity.
+2. Ensure you have root SSH access to the server.
+3. Run nixos-anywhere: `./bootstrap <servername>`
 
 ## Deployment
 
-### NEW
+Deployment can simply be done as follows: `deploy`
-
-`nix run github:numtide/nixos-anywhere -- --flake .#hypervisor root@jefke.hyp`
-
-### 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`.
-
-### NixOS deployment
-
-Finally, the NixOS definition can be deployed as follows: `nix run github:serokell/deploy-rs`.
