   2
   3 A simple GUI to make managing declarative nix-env easier
   4
   5 It has two buttons: "Edit Configuration" and "Apply Configuration"
   6
   7 The "Edit Configuration" button launches an editor on
   8 `~/.config/nixpkgs/overlays/userPackages.nix`, creating it with a
   9 useful template if it doesn't exist.  All you have to do is put the
  10 applications you want installed between the [ ] brackets.  For example,
  11 to add Firefox and LibreOffice, you'd type `firefox` and `libreoffice`
  12 where shown here:
  13
  14     final: prev: {
  15       userPackages = final.buildEnv {
  16         name = "userPackages";
  17         paths = (with final; [
  18
  19           firefox
  20           libreoffice
  21
  22         ];
  23       };
  24     }
  25
  26 Remember to save before pressing "Apply Configuration"!
  27
  28 The "Apply Configuration" button runs `nix-env -riA nixos.userPackages`,
  29 which makes your changes take effect.  Note that this **removes** any
  30 other packages that you may have installed imperatively with `nix-env -i`.
  31 Prefer declarative installation by listing everything you want installed
  32 in the "Edit Configuration" configuration file!
