 Stylix relies on [Home Manager](https://github.com/nix-community/home-manager)

-## Binary cache
-
-Stylix includes a Haskell program which generates color palettes.
-To avoid compiling this from source, add the following settings:
-
-```nix
-nix.settings = {
-  substituters = "https://danth.cachix.org";

 To get started, you need to set a wallpaper image.
