 A fast, native **macOS git client** — commit graph, branches, merges, rebases, working-copy diffs, and remotes — with **first-class commit-time editing**. Built with [Tauri 2](https://tauri.app) (Rust) and [SvelteKit 5](https://svelte.dev) (runes).
 
 > macOS only. The window uses native vibrancy (frosted-glass panels over the desktop) via `NSVisualEffect`.
 
+## Download
+
+**[⬇ Download the latest release](https://github.com/ashproto/git-it/releases/latest)** — open the `.dmg`, drag **Git It.app** into `/Applications`, and launch. It keeps itself up to date after that (in-app auto-updates, with an optional beta channel in Settings → Updates).
+
+> Requires **macOS 12.3+**. The release ships separate **Apple Silicon** and **Intel** builds — download the `.dmg` that matches your Mac (each runs fully native). In-app updates then track the right build automatically.

 ## Features
 
 - **Commit graph** — multi-lane history with curved or angular edges, ref badges (branches, tags, remotes, `HEAD`), infinite-scroll loading, and selectable rows.

 - **Commit-time editing** — select commits and shift them by an **offset**, set an **exact** time, or **compress** a range proportionally into a new window. Opens in an on-demand drawer; previews before it rewrites.
 - **Multi-repo** — open several repositories at once, as tabs or a sidebar list (your choice).
