fix web search setup in browser quickstart (#691)

 This launches the backend API server and a React frontend at [http://localhost:5173](http://localhost:5173).
 You get a ChatGPT-like interface with streaming responses, tool use, energy monitoring, and a telemetry dashboard — all running locally on your hardware.
 
+Web search is available through the built-in DuckDuckGo fallback. To use
+Tavily, add `TAVILY_API_KEY` under **Settings → Tools → Web Search** after the
+app starts, or export it before starting quickstart:
+
+```bash
+export TAVILY_API_KEY="tvly-..."
+./scripts/quickstart.sh
+```
+
+The script does not automatically source `.env` files. Run `source .env`
+first if that is where you keep the key. Stop any existing OpenJarvis server
+before restarting so it inherits the updated environment.
+
 To stop all services, press ++ctrl+c++ in the terminal.
