+defmodule Heroicons do
+  @moduledoc """
+  Provides precompiled icon compiles from [heroicons.com v<%= @vsn %>](heroicons.com).
+
+  Heroicons are designed by [Steve Schoger](https://twitter.com/steveschoger)
+
+  ## Usage
+
+  Hero icons come in three styles – outline (`24x24`), solid (`24x24`), and mini (`20x20`).
+
+  By default, the icon components will use the outline style, but the `solid` or
+  `mini` attributes may be passed to select styling, for example:
+
+  ```heex
+  <Heroicons.cake />
+  <Heroicons.cake solid />
+  <Heroicons.cake mini />
+  ```
+
+  You can also pass arbitrary HTML attributes to the components:
+
+   ```heex
+  <Heroicons.cake class="w-2 h-2" />
+  <Heroicons.cake solid class="w-2 h-2" />
+  ```
