 - Bei Domainwechsel passen BASE_URL/PAYTO in der `.env` ebenfalls an (Templates rendern automatisch beim Start).
 - Direktes Port-Mapping (8080/8081/9966) kannst du entfernen, wenn nur Caddy nach außen gehen soll.
 
+## WordPress/WooCommerce (optional)
+- Services `mariadb`, `wordpress`, `wp-init`. `wp-init` installiert bei Bedarf Core, WooCommerce und das Plugin `gnu-taler-payment-for-woocommerce`.
+- Env in `.env` setzen (`WP_DB_*`, `WP_URL`, Admin-Creds, `WORDPRESS_HOST`); Default-Port 8085 oder über Caddy (`WORDPRESS_HOST`).
+
 ## Hinweise
 - Passwörter in `.env` müssen zu `postgres/init/01-init-taler.sh` passen (wird automatisch per Env gesetzt).
 - Master-Key muss stabil bleiben; nur Pfad mounten, nicht neu generieren.
