## Overview

RHI is a Windows game-library manager for installing and maintaining HDR mods, ReShade, upscalers, shader packs, frame limiters, and NVIDIA settings. The main user flow is discover or add games, view per-game controls, then install or configure components in game folders; background update orchestration maintains them afterward. Groups and paths reflect the supplied tree and README. Several service implementations were not sampled, so their internal call wiring is intentionally left out.

Main entry points: [`RenoDXCommander/ViewModels/GameCardViewModel.cs`](https://github.com/rankftw/rhi/blob/main/RenoDXCommander/ViewModels/GameCardViewModel.cs) (Game controls), [`RenoDXCommander/ViewModels/MainViewModel.cs`](https://github.com/rankftw/rhi/blob/main/RenoDXCommander/ViewModels/MainViewModel.cs) (Library view model), [`RenoDXCommander/Services/UpdateOrchestrationService.cs`](https://github.com/rankftw/rhi/blob/main/RenoDXCommander/Services/UpdateOrchestrationService.cs) (Update orchestration), [`RenoDXCommander/MainWindow.xaml.cs`](https://github.com/rankftw/rhi/blob/main/RenoDXCommander/MainWindow.xaml.cs) (Main window)
