Missing attribute 'overlay'

Describe the issue

The documentation mentions an overlay that can be used to pass things to pkgs:

pkgs = nixpkgs.legacyPackages.${system}.extend poetry2nix.overlay;

I've attempted two ways below to use that overlay. None of them work, and I get:

       error: attribute 'overlay' missing
       at /nix/store/xq0f0bh60g2dmxhjrhq753xcii8xi92a-source/flake.nix:13:56:
           12|       let
           13|         pkgs = nixpkgs.legacyPackages.${system}.extend poetry2nix.overlay;

Additional context

default.nix/shell.nix/flake.nix:

{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable-small";
    flake-utils.url = "github:numtide/flake-utils";
    poetry2nix = {
      url = "github:nix-community/poetry2nix";
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };
  outputs = { self, nixpkgs, flake-utils, poetry2nix }:
    flake-utils.lib.eachDefaultSystem (system:
      let
        # Version in the docs
        pkgs = nixpkgs.legacyPackages.${system}.extend poetry2nix.overlay;

        # What I was trying to run before
        overlays = [ poetry2nix.overlay ];
        pkgs = import nixpkgs { inherit system overlays; };
      in
      with pkgs;
      {
        packages = {
          default = self.packages.${system}.app;
          app = mkPoetryApplication {
            projectDir = self;
          };
        };

        devShells.default = mkShell {
          inputsFrom = [ self.packages.${system}.app ];
        };

        devShells.poetry = mkShell {
          packages = [ poetry ];
        };
      }
    );
}

Looks like it should be poetry2nix.overlays.default? FAQ should probably also be updated.
