 Watch videos together in real-time. Each user loads a local video file — only sync commands and chat messages travel over the network.
 
+## Architecture
+
+This project consists of three main components:
+
+- **Server**: A fast, lightweight WebSocket server built with Bun.
+- **Web Frontend**: A vanilla HTML/CSS/JS single-page application for joining rooms and syncing video playback.
+- **Desktop App**: A Python/PyQt6 application with embedded VLC (`python-vlc`). **Note:** The desktop client was specifically created because web browsers (like Chrome) have issues handling and playing MKV files natively.
+
 ## Features
 
-- **Room system** — create a room, share the 6-character code with friends
-- **File verification** — joiners must have the exact same file (matched by name + size)
-- **Playback sync** — play, pause, seek, and speed changes broadcast to all clients instantly
-- **Drift correction** — automatic re-sync every 5 seconds to keep everyone aligned
-- **Live chat** — YouTube-style chat sidebar with colored usernames
-- **Local playback** — multi-gigabyte files work fine since nothing is uploaded

+- **Broad format support** — the desktop app leverages VLC to play MKV and other formats that browsers struggle with.
 
 ## Quick Start
 
+### 1. Start the Server
+
 ```bash
 # Install Bun (if not already installed)
 curl -fsSL https://bun.sh/install | bash
@@ -21,15 +32,44 @@ curl -fsSL https://bun.sh/install | bash
 bun run server.ts
 ```
 
-Open **http://localhost:3000** in your browser.
+### 2. Connect via Web Frontend
 
-## How It Works
+Once the server is running, open **http://localhost:3000** in your browser to access the web app.
 
 1. Enter your name and select a video file → **Create Room**
 2. Share the room code with a friend
 3. Friend enters the code → **Join Room** → selects their copy of the same file
 4. Play/pause/seek in either browser — the other stays in sync
 
+### 3. Connect via Desktop App (Recommended for MKV files)
+
+If you are playing MKV files or formats not supported by your browser, use the desktop client:
+
+```bash
+cd desktop-client
+
+# Install dependencies using uv
+uv sync
+
+# Run the app
+uv run main.py
+```
+
+You can also build a standalone executable for the desktop app using the provided `build.ps1` script (requires PyInstaller).
+
+### Quick Run on Linux
+
+If you just want to run the desktop client without cloning the repo manually, use the launcher script. Prerequisites: `git` and [`uv`](https://docs.astral.sh/uv/).
+
+```bash
+# Download the script
+curl -fsSL https://gitea.peterstockings.com/peterstockings/video-sync/raw/branch/master/desktop-client/run-videosync.sh -o run-videosync.sh
+chmod +x run-videosync.sh
+
+# Run (clones on first launch, pulls updates on subsequent runs)
+./run-videosync.sh
+```
