+## Overview
 
-Rivet Icons are a set of SVG icons that are used in Rivet products. This package is built on top of great Font Awesome icons. Some icons used in our products are from the premium Font Awesome icon set. We've created a package that lets you use premium icons without having to buy a Font Awesome license.
+Rivet Icons is an icon library built on Font Awesome that provides pre-generated SVG icons for use in Rivet products. All icons (including Pro icons) are committed to the repository, making this package work out-of-the-box with **no Font Awesome token required** for end users.
