Install
This is the repository archive. It installs, but the folder name will carry the branch suffix and updates will not flow.
Install straight from GitHub with WP-CLI:
wp plugin install https://github.com/creativelittledots/woocommerce-attribute-descriptions/archive/refs/heads/master.zipWooCommerce Attribute Descriptions
WooCommerce Attribute Descriptions extends WooCommerce and adds customisable descriptions to Product Attributes on Variable Products
Sometimes you need to provide more information regarding product attributes, especially when customers have to decipher what they need from a variable product, WooCommerce Attribute Descriptions provides this exact functionality.
Note: This only works with attributes that are added via Products > Attributes and does not currently work with arbitrary attributes added at Single Product level.
How it works

Simple enter some descriptive content in to the newly added text area on a Product Attribute.

When adding the Attribute to a Product, lets say a Variable Product for example, you will see a question mark next the attribute name on the Single Product template.

When you click on the question mark you will be able to read the Product Attribute content.
Features
All of the templates in the templates/ folder are overridable by including the file(s) in your theme folder.
