In the example above, you can see the description, the input specified as a GitHub repository with a specific branch (here nixos/nixpkgs on the nixos-unstable branch), and an output that makes use of the input. The output simply specifies that the flake contains one package for the x86_64 architecture called hello. Even if your flake's output wouldn't use its input (however, in practice, that is highly unlikely), the output still needs to be a Nix function.
