 <p>There are a set of several templates that control the checkout page. They can be found in the WooCommerce plugin folder in templates/checkout.</p> <p>You can put a woocommerce/templates/checkout folder inside your theme's folder and copy the templates you want to alter into it. Those will override the normal templates without altering the plugin itself. That way your changes won't get overwritten when WooCommerce is updated.</p>
