 There is also an `hmModules` attribute set for pulling home-manager modules in

+flake.nix:

 ```nix
 {
   hmModules = {

+    inherit doom-emacs;
+  };
+}
+```

+### Use:
+users/nixos/default.nix:
+```nix
+{ hmModules, ... }:
+{
+  home-manager.users.nixos = {
+    imports = [ hmModules.doom-emacs.hmModule ] ;

+    programs.doom-emacs.enable = true;
   };
 }
