-
-The `iron-icon` element displays an icon. By default an icon renders as a 24px square.
-
-Example using src:
-
-    <iron-icon src="star.png"></iron-icon>
-
-Example setting size to 32px x 32px:
-
-    <iron-icon class="big" src="big_star.png"></iron-icon>
-
-    <style is="custom-style">
-      .big {
-        --iron-icon-height: 32px;
-        --iron-icon-width: 32px;
-      }
-    </style>
-
-The iron elements include several sets of icons.
-To use the default set of icons, import  `iron-icons.html` and use the `icon` attribute to specify an icon:
-
-    &lt;!-- import default iconset and iron-icon --&gt;
-    <link rel="import" href="/components/iron-icons/iron-icons.html">
-
-    <iron-icon icon="menu"></iron-icon>
-
-To use a different built-in set of icons, import  `iron-icons/<iconset>-icons.html`, and
-specify the icon as `<iconset>:<icon>`. For example:
-
-    &lt;!-- import communication iconset and iron-icon --&gt;
-    <link rel="import" href="/components/iron-icons/communication-icons.html">
-
-    <iron-icon icon="communication:email"></iron-icon>
-
-You can also create custom icon sets of bitmap or SVG icons.
-
-Example of using an icon named `cherry` from a custom iconset with the ID `fruit`:
-
-    <iron-icon icon="fruit:cherry"></iron-icon>
-
-See [iron-iconset](#iron-iconset) and [iron-iconset-svg](#iron-iconset-svg) for more information about
-how to create a custom iconset.
-
-See [iron-icons](https://elements.polymer-project.org/elements/iron-icons?view=demo:demo/index.html) for the default set of icons.
