+The `iron-iconset` element allows users to define their own icon sets.
+The `src` property specifies the url of the icon image. Multiple icons may
+be included in this image and they may be organized into rows.
+The `icons` property is a space separated list of names corresponding to the
+icons. The names must be ordered as the icons are ordered in the icon image.
+Icons are expected to be square and are the size specified by the `size`
+property. The `width` property corresponds to the width of the icon image
+and must be specified if icons are arranged into multiple rows in the image.
+
+All `iron-iconset` elements are available for use by other `iron-iconset`
+elements via a database keyed by id. Typically, an element author that wants
+to support a set of custom icons uses a `iron-iconset` to retrieve
+and use another, user-defined iconset.
+
+Example:
+
+    <iron-iconset id="my-icons" src="my-icons.png" width="96" size="24"
+        icons="location place starta stopb bus car train walk">
+    </iron-iconset>
+
+This will automatically register the icon set "my-icons" to the iconset
+database.  To use these icons from within another element, make a
+`iron-iconset` element and call the `byId` method to retrieve a
+given iconset. To apply a particular icon to an element, use the
+`applyIcon` method. For example:
+
+    iconset.applyIcon(iconNode, 'car');
+
+Themed icon sets are also supported. The `iron-iconset` can contain child
+`property` elements that specify a theme with an offsetX and offsetY of the
+theme within the icon resource. For example.
+
+    <iron-iconset id="my-icons" src="my-icons.png" width="96" size="24"
+        icons="location place starta stopb bus car train walk">
+      <property theme="special" offsetX="256" offsetY="24"></property>
+    </iron-iconset>
+
+Then a themed icon can be applied like this:
+
+    iconset.applyIcon(iconNode, 'car', 'special');
