+# RustDesk Web Client
+
+OSS-compatible web client for [RustDesk](https://rustdesk.com) remote desktop, built from the official Flutter web source with patches for hbbs/hbbr (non-Pro) servers.
+
+## Quick Start
+
+```bash
+docker run -d -p 8080:80 \
+  -e RUSTDESK_HOST=wss://your-server.com/hbbs \
+  -e RUSTDESK_RELAY=wss://your-server.com/hbbr \
+  -e RUSTDESK_KEY=your-public-key \
+  rophy/rustdesk-webclient
+```
+
+Then open http://localhost:8080 in a browser.
+
+## Environment Variables
+
+| Variable | Required | Description |
+|----------|----------|-------------|
+| `RUSTDESK_HOST` | Yes | WebSocket URL of the rendezvous server (hbbs) |
+| `RUSTDESK_RELAY` | No | WebSocket URL of the relay server (hbbr). Defaults to `RUSTDESK_HOST` |
+| `RUSTDESK_KEY` | No | Server public key |
+| `RUSTDESK_API` | No | API server URL (only for Server Pro) |
+
+## With Reverse Proxy
+
+When running behind a reverse proxy (nginx, Istio, etc.) that terminates TLS:
+
+```bash
+docker run -d -p 8080:80 \
+  -e RUSTDESK_HOST=wss://rustdesk.example.com/hbbs \
+  -e RUSTDESK_RELAY=wss://rustdesk.example.com/hbbr \
+  -e RUSTDESK_KEY=your-public-key \
+  rophy/rustdesk-webclient
+```
+
+The proxy should route `/hbbs` to hbbs port 21118 and `/hbbr` to hbbr port 21119 with WebSocket upgrade support.
