  #### OPTION A
  #### Plainly use https://github.com/nix-community/nix-doom-emacs/blob/master/docs/reference.md#flake
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixpkgs-unstable";

  #### OPTION B
  #### Wrap nix-doom-emacs in each-system
  #### This will likely get it to work on Darwin and Linux
  #### https://github.com/numtide/flake-utils/blob/main/examples/each-system/flake.nix

  #       packages = rec {
  #         hello = pkgs.hello;
