+# Copy and adjust environment variables (optional)
+cp docker/.env-dist .env
+
+# Build and start
+docker compose build
+docker compose up -d
+
+# WordPress installs automatically on first boot (admin/admin)

+# → http://localhost:8080/wp-admin/

+# Tear down
+docker compose down -v

+The image preinstalls WooCommerce and wp-bootstrap. The override bind-mounts both themes for live development.
