+
+`paper-icon-button` is a button with an image placed at the center. When the user touches
+the button, a ripple effect emanates from the center of the button.
+
+`paper-icon-button` includes a default icon set.  Use `icon` to specify which icon
+from the icon set to use.
+
+    <paper-icon-button icon="menu"></paper-icon-button>
+
+See [`iron-iconset`](#iron-iconset) for more information about
+how to use a custom icon set.
+
+Example:
+
+    <link href="path/to/iron-icons/iron-icons.html" rel="import">
+
+    <paper-icon-button icon="favorite"></paper-icon-button>
+    <paper-icon-button src="star.png"></paper-icon-button>
+
+Styling
+-------
+
+Style the button with CSS as you would a normal DOM element. If you are using the icons
+provided by `iron-icons`, they will inherit the foreground color of the button.
+
+    /* make a red "favorite" button */
+    <paper-icon-button icon="favorite" style="color: red;"></paper-icon-button>
+
+By default, the ripple is the same color as the foreground at 25% opacity. You may
+customize the color using this selector:
+
+    /* make #my-button use a blue ripple instead of foreground color */
+    #my-button::shadow #ripple {
+      color: blue;
+    }
+
+The opacity of the ripple is not customizable via CSS.
