Via ZIP upload:
- Download the plugin ZIP file from your WooCommerce account or purchase confirmation email.
- In your WordPress admin, go to Plugins → Add New → Upload Plugin.
- Click Choose File, select the ZIP, and click Install Now.
- Click Activate Plugin.
After activation, the “Mix and Match” product type becomes available in the WooCommerce product editor. There are no global settings pages — all configuration is done at the product level in the Mix & Match tab.
