+- URL: `http://${main_domain}`
+- Administrator username: the configured `admin_username` value
+- Administrator password: the generated `admin_password` value
+- Administrator email: the configured `admin_email` value
+
+The template uses Joomla's auto-deployment environment variables so the site and administrator account are initialized on first start.
+
+## Storage
+
+The template creates persistent volumes for:
+
+- Joomla application files at `/var/www/html`
+- MariaDB data at `/var/lib/mysql`
+
+Back up both volumes together before upgrades or migrations.
