12+
13+Or compile directly:

15+```sh

23+ [--no-color] [--json] [--version] [--help]

25+
26+The implementation targets Linux first, with basic macOS and Windows fallbacks.
27+Missing optional commands such as `lspci`, `ip`, or a package manager are shown
28+as `Unknown` instead of causing the program to fail.
