-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:
+This repo could be used in the past as a module. While still technically possible, it is not recommended
+because the amounts of flake inputs highly increased and the modules are not designed with that in mind.
