## Overview

gudumpinfo is a graphical UEFI Shell system-information viewer. The principal workflow is to launch the EFI application, choose an information view, and inspect firmware or hardware state; supported views can also save and replay captured data. The repository contains prebuilt EFI images and manuals, but no source tree or source excerpts, so the graph reflects README-documented capabilities and does not infer internal module boundaries or undocumented call wiring.

Main entry points: [`GudumpInfo.efi`](https://github.com/mikewuping/gudumpinfo/blob/main/GudumpInfo.efi) (Search and navigation)
