+Special thanks to [Nixpkgs] and [Home-Manager]. The interface of the
+`hjem.users` module is inspired by Home-Manager's `home.file` and nixpkgs'
+`users.users` modules. What is now Hjem also started as an experimental module
+addition to Nixpkgs' `users.users`. Hjem would not be possible without any of
+those projects, thank you!
+
+A worthy project of note is [Hjem Rum](https://github.com/snugnug/hjem-rum) by
+[@LunarNovaa](https://github.com/lunarnovaa) that establishes a module system,
+similar to the one of Home-Manager, for users less comfortable with manually
+linking files in place. If you wish to utlize the power of Hjem, but want an
+easier interface we encourage you to take a look at Hjem-Rum.
