+The `core-tooltip` element creates a hover tooltip centered for the content
+it contains. It can be positioned on the top|bottom|left|right of content using
+the `position` attribute.
+
+To include HTML in the tooltip, include the `tip` attribute on the relevant
+content.
+
+<b>Example</b>:
+
+    <core-tooltip label="I'm a tooltip">
+      <span>Hover over me.</span>
+    </core-tooltip>
+
+<b>Example</b> - positioning the tooltip to the right:
+
+    <core-tooltip label="I'm a tooltip to the right" position="right">
+      <polymer-ui-icon-button icon="drawer"></polymer-ui-icon-button>
+    </core-tooltip>
+
+<b>Example</b> - no arrow and showing by default:
+
+    <core-tooltip label="Tooltip with no arrow and always on" noarrow show>
+      <img src="image.jpg">
+    </core-tooltip>
+
+<b>Example</b> - rich tooltip using the `tip` attribute:
+
+    <core-tooltip>
+      <div>Example of a rich information tooltip</div>
+      <div tip>
+        <img src="profile.jpg">Foo <b>Bar</b> - <a href="#">@baz</a>
+      </div>
+    </core-tooltip>
