+
+On the eCommerce product page, the "Specifications" table added by
+``website_sale_comparison`` lists every attribute of the product,
+including non-variant-defining ("informative") attributes whose values
+can be restricted to specific variant combinations via the attribute
+value's "Exclude for" configuration.
+
+Without this module, that table always lists every configured value of
+such an attribute, and never updates when the customer changes the
+selected variant. This module makes it show only the value(s) actually
+compatible with the combination currently selected on the page, and
+refreshes that table when the customer changes variant.
+
+**Table of contents**
+
+.. contents::
+   :local:
+
+Usage
+=====
+
+1. Go to *Website > Products > Attributes*.
+2. On a non-variant-defining attribute's value, configure "Exclude for"
+   to list the variant-defining value(s) it is incompatible with.
+3. On the eCommerce product page, the "Specifications" table will only
+   show the value(s) of that attribute compatible with the currently
+   selected variant, and will update automatically when the customer
+   changes it.
