 Add your gpg-id to the .gpg-id file in secrets and let somebody reencrypt it for you.
 Maybe this works for you, maybe not. I did it somehow:
-```PASSWORD_STORE_DIR=`pwd` tr '\n' ' ' < .gpg-id | xargs -I{} pass init {}````
+
+```
+PASSWORD_STORE_DIR=`pwd` tr '\n' ' ' < .gpg-id | xargs -I{} pass init {}
+```
 
 Your gpg key has to have the Authenticate flag set. If not update it and push it to a keyserver and wait.
 This is necessary, so you can login to any machine with your gpg key.

+
+This repository contains a NixOS module that can be used with personal machines 
+as well. This module appends `/etc/ssh/ssh_known_hosts` with the host keys of 
+registered HQ hosts, and optionally appends `/etc/hosts` with static IPv6 
+addresses local to HQ. Simply import the `lib` directory to use the module. As 
+an example:
+
+```nix
+# /etc/nixos/configuration.nix
+{ config, pkgs, lib, ... }:
+let
+  c3d2Config =
+    builtins.fetchGit { url = "https://gitea.c3d2.de/C3D2/nix-config.git"; };
+in {
+  imports = [
+    # ...
+    "${c3d2Config}/lib"
+  ];
+
+  c3d2 = {
+    isInHq = false; # not in HQ, this is the default.
+    mapHqHosts = true; # Make entries in /etc/hosts for *.hq internal addresses.
+    enableMotd = true; # Set the login shell message to the <<</>> logo.
+  };
+
+  # ...
+}
+
+```
