+# Willem
+
+Willem is a server running on a Raspberry Pi 400 offering the following services:
+- [Gitea](git.vatthauer.xyz)
+- [Vaultwarden](bitwarden.vatthauer.xyz)
+
+There are daily backups of the Gitea instance using Restic via B2.
+## Installation on Raspberry Pi 400
+### Resources
+- https://nixos.wiki/wiki/NixOS_on_ARM/Raspberry_Pi_4
+- https://nixos.wiki/wiki/NixOS_on_ARM#Installation
+
+### Step by step
+1. Follow the [generic installation steps](https://nixos.wiki/wiki/NixOS_on_ARM#Installation) to get NixOS up and running on the Pi.
+2. Generate the default `configuration.nix` via `sudo nixos-generate-config` and do a first rebuild `sudo nixos-rebuild switch`
+3. Somehow get this repository onto the machine and `cd` into it
+4. We need git: `nix-shell -p git`
+5. Build the flake via `sudo nixos-rebuild switch --flake .`
+6. At this point you can restart
+7. Login, set password, move the repository to `/home/leonv/nixos`
