Hi,
I am very new to NixOS and had difficulty in following your installation instructions. I tried modifying my ~/.config/home-manager/flake.nix file as recommended for the standalone home manager installation and kept getting "undefined variable: nix-colors" error. Please see below my flake.nix file.

`{
description = "Home Manager configuration of user";

inputs = {
# Specify the source of Home Manager and Nixpkgs.
nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
nix-colors.url = "github:misterio77/nix-colors";
home-manager = {
url = "github:nix-community/home-manager";
inputs.nixpkgs.follows = "nixpkgs";
};
};

outputs = { nixpkgs, home-manager, ... }:
let
system = "x86_64-linux";
pkgs = nixpkgs.legacyPackages.${system};
in {
homeConfigurations."user" = home-manager.lib.homeManagerConfiguration {
inherit pkgs;
# Specify your home configuration modules here, for example,
# the path to your home.nix.
modules = [ ./home.nix ];
# Optionally use extraSpecialArgs
# to pass through arguments to home.nix
extraSpecialArgs = { inherit nix-colors; };
};
};
}`

I appreciate any pointers about what I am doing wrong.
