My plan for full migration into NixOS and Wayland

hi there. if you have a chance, can you please explain the desktop.nix file? I'm not sure how it works and I haven't found anything like it out there. is this basically a module you can import into a config (homemanager or regular) and it will build everything defined in desktopEnvironment?

thanks for posting this/any extra info you may give!
