+
+## Deployment
+
+### Testing Your Changes
+- Test with 2 participants (P2P mode)
+- Test with 3+ participants (JVB mode)
+- Verify audio/video in both modes
+- Test on mobile apps if changes affect mobile
+
+### Browser Support
+The app supports:
+- Chrome/Chromium
+- Firefox
+- Safari
+- Edge
+
+### Beta Testing
+Beta testing available at https://beta.meet.jit.si/
+
+## Troubleshooting
+
+**Certificate warnings in development?** This is normal with self-signed certificates.
+
+**P2P works but 3+ participants fail?** Check UDP 10000 for JVB/firewall issues.
+
+**Works on web, fails on mobile?** TLS certificate chain issue - ensure fullchain.pem is present.
