+> This is a **Developer level** doc. If you are unfamiliar with code and resolving potential conflicts, select a [WooExpert or Developer](https://woocommerce.com/customizations/) for assistance. We are unable to provide support for customizations under our [Support Policy](http://www.woocommerce.com/support-policy/).

+Add this code to your child theme’s `functions.php` file or via a plugin that allows custom functions to be added, such as the [Code Snippets](https://wordpress.org/plugins/code-snippets/) plugin. Avoid adding custom code directly to your parent theme’s functions.php file, as this will be wiped entirely when you update the theme.
