-Caddy automatically handles HTTPS with Let's Encrypt!
+**That's it!** Caddy automatically:
+- Obtains SSL certificate from Let's Encrypt
+- Handles WebSocket upgrades
+- Redirects HTTP to HTTPS
+- Renews certificates automatically
+
+See `Caddyfile.example` for advanced configuration with security headers, logging, and optional features.
