 - Keeps the API key secure from browser developer tools
 - Provides a single point for API request/response logging
 
+**The proxy server is automatically started when you run `npm start`** and runs on port 3001 alongside the Vite dev server (port 5173).
+
+#### Troubleshooting the Proxy Server
+
+If you encounter errors like "Failed to fetch" or "Network request failed" when generating briefings:
+
+1. **Check if the proxy server is running**: Look for console output showing `Proxy server listening on port 3001`
+2. **Restart the application**: The easiest way to restart both servers is to:
+   - Stop the current process (Ctrl+C in terminal)
+   - Run `npm start` again
+
+If you need to run the servers separately for debugging:
+```bash
+# Terminal 1: Run proxy server only
+npm run proxy
+
+# Terminal 2: Run Vite dev server only
+npm run dev
+```
