Sometimes, deeper customizations in the way WooCommerce products and content are displayed require template overrides. This is normally done via template files in your theme folder, but since Oxygen disables the theme system, we've added a special WooCommerce override template path to allow template overrides.
First, create this path in the wp-content folder on your site: /oxywoocotemplates/woocommerce/
You can now follow the normal WooCommerce instructions at https://woocommerce.com/document/template-structure/ for overriding templates by adding them (using the exact path WooCo indicates) in the wp-content/oxywoocotemplates/woocommerce/ folder.
