+# Alfred Proxy Systemd Service
+
+## Service Management
+
+```bash
+# Status
+systemctl --user status alfred-proxy
+
+# Start
+systemctl --user start alfred-proxy
+
+# Stop
+systemctl --user stop alfred-proxy
+
+# Restart
+systemctl --user restart alfred-proxy
+
+# Enable (auto-start)
+systemctl --user enable alfred-proxy
+

+systemctl --user disable alfred-proxy
+
+# View logs
+journalctl --user -u alfred-proxy -f
+
+# View proxy-specific logs
+tail -f /tmp/alfred-proxy.log
+```
+
+## Auto-Restart
+
+The service is configured with:
+- **Restart=always** - Always restart on failure
+- **RestartSec=5** - Wait 5 seconds between restarts
+
+## Error Handling Improvements
+
+Added to `server.js`:
+1. **Global exception handler** - Catches uncaught exceptions
+2. **Global rejection handler** - Catches unhandled promise rejections
+3. **Proper interval cleanup** - Clears ping intervals on disconnection
+
+These prevent the service from crashing on unexpected errors.
+
