 - remove any darwin code (I don't use or plan to use a mac)
 - assume wayland (for example electron wayland flags hard-coded)
 
-and if you do want to use these with the overlay (recommended) add this
-to your nixos config

+### oki but how 2 use?!?
+
+just add this to your flake.nix inputs (nix channel users cope)
+```nix
+  haipkgs = {
+    url = "git+https://git.blahai.gay/blahai/haipkgs.git";
+    inputs = {
+      nixpkgs.follows = "nixpkgs";
+    };
+  };
+
+```
+
+then add this to your config somewhere
 ```nix
 nixpkgs.overlays = [
   inputs.haipkgs.overlays.default
 ];
 ```
 
+and congrats you can now use haipkgs 🎉
