• Use child themes for customizations to preserve update compatibility
• Support internationalization (i18n) with WordPress localization functions

WooCommerce

• Override templates in your-plugin/woocommerce/ directory
• Use CRUD classes and data stores for custom data management
• Apply WC()->session->set() for temporary data storage
