 I have automated myself out of a job. How to use:

 1. Boot into installer
-2. Unlock luks partition
-3. Run the following commands:

+2. Unlock luks partition
+
+3. Connect to the internet with `nmcli`
+
+  - Scan for available networks:
+
+    ```bash
+    nmcli device wifi list
+    ```
+  - For an open network:
+
+    ```bash
+    nmcli device wifi connect "<SSID>"
+    ```
+  - For a secured network:
+
+    ```bash
+    nmcli device wifi connect "<SSID>" password "<password>"
+    ```
+
+4. Run `sudo nix-install /etc/nixos -m install|repair -h host [-k key] [-c] [-r]"`
+
+## Reinstalling the Installer
+
+1. Download a Minimal Live Nix ISO
+
+  - Visit the official NixOS website: [https://nixos.org/download.html](https://nixos.org/download.html).
+  - Download the "Minimal ISO image".
+
+2. Burn the ISO
+
+  - On Windows, use [Rufus](https://rufus.ie) to burn the ISO to a USB drive.
+
+  - On Linux, use the `dd` command:
+
+    ```bash
+    sudo dd if=<path-to-iso> of=/dev/sdX bs=4M status=progress
+    ```
+
+3. Boot into USB
+
+4. Connect to the Internet with `wpa_supplicant`
+
+  - Identify your network interface:
+
+    ```bash
+    ip link show | grep -E '^[0-9]+:' | awk '{print $2}' | tr -d ':'
+    ```
+  - For an open network:
+
+    ```bash
+    wpa_supplicant -i "${interface}" -c <(wpa_passphrase "${ssid}") -B
+    ```
+
+  - For a secured network:
+
+    ```bash
+    config=$(mktemp)
+    wpa_passphrase "${ssid}" "${passphrase}" > "${config}"
+    wpa_supplicant -i "${interface}" -c "${config}" -B
+    rm "${config}"
+    ```
+
+  - Obtain an IP address:
+
+    ```bash
+    dhcpcd
+    ```
+
+5. Clone the flake repository
+
+   ```bash
+   git clone git.karaolidis.com/karaolidis/nix
+   cd nix
   ```
-   cd /etc/nixos
-   direnv allow
-   sudo ./lib/scripts/install.sh
-   ```
+
+6. I really hope you had a backup of the keys, because you must copy them to the repository before the next step.
+
+7. Run `nix --experimental-features "nix-command flakes" shell nixpkgs#disko nixpkgs#jq -c bash hosts/common/configs/system/nix-install/install.sh nix -m install -h installer -k personal -c`
