 [Heroicons](https://github.com/tailwindlabs/heroicons) are "a set of free MIT-licensed high-quality SVG icons for you to use in your web projects". This package gives you Elixir functions to drop Heroicons into your HTML, styled with arbitrary classes.
 
+This library provides optimized svgs for each Heroicon packaged as a Phoenix Component (and as a function for backwards-compatibility).
+
+In order to provide the best balance of fast compilation times and run-time performance, Phoenix Components are just-in-time compiled on first use and then cached in an ETS-backed cache.
