## Overview

SourceGit is a cross-platform Git GUI. The principal workflow is opening a repository, viewing its state and history, then invoking Git operations through the interface and inspecting the result. The README also documents dedicated capabilities for diffs and file history, collaboration, repository organization, Git LFS, and AI-assisted commit messages. The graph uses the tree and sampled code; links within unsampled feature areas are included only where the README or sampled call sites support them.

Main entry points: [`src/Commands/Command.cs`](https://github.com/weiningwei/sourcegit/blob/master/src/Commands/Command.cs) (Git command layer), [`src/ViewModels/Repository.cs`](https://github.com/weiningwei/sourcegit/blob/master/src/ViewModels/Repository.cs) (Repository workspace), [`src/ViewModels/Launcher.cs`](https://github.com/weiningwei/sourcegit/blob/master/src/ViewModels/Launcher.cs) (Repository launcher), [`src/ViewModels/WorkingCopy.cs`](https://github.com/weiningwei/sourcegit/blob/master/src/ViewModels/WorkingCopy.cs) (Working copy)
