I'm new with nix-darwin. I'm attempting to use it to manage homebrew packages but failing immediately

➜ darwin-rebuild switch --flake ~/.config/nix-darwin

There is a package out there called nix-homebrew that does install homebrew by default the homebrew option doesn't install homebrew so either you have to install it the offical way or nix-homebrew.
