## Provisioning New Devices
1. Create `hosts/$HOSTNAME/default.nix` and other host-specific nix modules (e.g. `disko.nix`,`hardware.nix`, and `home.nix`).
2. Add host to `nixosConfigurations` in `flake.nix`.
3. (OPTIONAL) Generate a `cert.pem`, `key.pem`, and device ID for Syncthing with `syncthing -generate=$HOSTNAME`. Find the device ID in the generated `config.xml` and add it to `nixosModules/services/syncthing/default.nix`, encrypt the cert and key with agenix, and set them as appropriate in the host configuration.
4. Install NixOS from this flake. Secrets will _not_ be available on first boot.
5. Copy the new system's public SSH key (`/etc/ssh/ssh_host_ed25519_key.pub`) to the host configuration (`host/$HOSTNAME/ssh.pub`).
6. Add the new public key to `secrets/secrets.nix` and rekey all secrets with `agenix --rekey`.
7. Rebuild the new system from git. Secrets will be automatically decrypted and immediately available in `/run/agenix/`.
8. (OPTIONAL) Generate a new user SSH key and add it to `nixosModules/users/default.nix` in order to enable passwordless logins to other hosts.

## WiFi
WiFi networks can be configured declratively in `nixosModules/system/wifi.nix` using `networking.networkmanager.ensureProfiles.profiles`, provided by nixpkgs.
### Generating WiFi Profiles
[nm2nix](https://github.com/janik-haag/nm2nix) can generate nix-compatible code for all the WiFi networks in `/etc/NetworkManager/system-connections/` and `/run/NetworkManager/system-connections`.
```bash
sudo su -c "cd /etc/NetworkManager/system-connections && nix --extra-experimental-features 'nix-command flakes' run github:Janik-Haag/nm2nix | nix --extra-experimental-features 'nix-command flakes' run nixpkgs#nixfmt-rfc-style"
