WordPress allows theme developers to make their themes customizable through advanced PHP solution called hooks. There are 2 types of hooks: actions and filters. Chipmunk uses filter functionality to allow advanced users to modify some parts of the theme.
To be able to use our custom filters, you’ll need to create a child theme or use our example child theme available to download here.
