This is a Developer level doc. If you are unfamiliar with code/templates and resolving potential conflicts, select a WooExpert or Developer for assistance. We are unable to provide support for customizations under our  Support Policy.

Add 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 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.
