-[nixos-facter](https://github.com/numtide/nixos-facter) command, which offers

+nixos-facter module is included in nixpkgs and automatically configures drivers,
+kernel modules, firmware, and various hardware support based on the detected

-To use `nixos-facter`, add the following to your flake inputs:
-
-```diff
- {
-+ inputs.nixos-facter-modules.url = "github:numtide/nixos-facter-modules";
- }

-Next, import the module into your configuration and specify `facter.json` as the
-path where the hardware report will be saved:

 To generate the configuration for `nixos-facter` with `nixos-anywhere`, use the
 following flags: `--generate-hardware-config nixos-facter ./facter.json`. The
-second flag, `./facter.json`, specifies where `nixos-generate-config` will store
-the hardware report. Adjust this path to suit the location where you want the
