+Material design: [Surface reaction](https://www.google.com/design/spec/animation/responsive-interaction.html#responsive-interaction-surface-reaction)
+
 `paper-ripple` provides a visual effect that other paper elements can
 use to simulate a rippling effect emanating from the point of contact.  The
 effect can be visualized as a concentric circle with motion.
 
 Example:
 
-```html
-<paper-ripple></paper-ripple>
-```
+    <div style="position:relative">
+      <paper-ripple></paper-ripple>
+    </div>
+
+Note, it's important that the parent container of the ripple be relative position, otherwise
+the ripple will emanate outside of the desired container.
 
 `paper-ripple` listens to "mousedown" and "mouseup" events so it would display ripple
 effect when touches on it.  You can also defeat the default behavior and
 manually route the down and up actions to the ripple element.  Note that it is
-important if you call downAction() you will have to make sure to call
-upAction() so that `paper-ripple` would end the animation loop.

 Example:

-  upAction: function(e) {
-    this.$.ripple.upAction();

+    <paper-ripple id="ripple" style="pointer-events: none;"></paper-ripple>
+    ...
+    downAction: function(e) {
+      this.$.ripple.downAction({x: e.x, y: e.y});
+    },
+    upAction: function(e) {
+      this.$.ripple.upAction();
+    }
 
 Styling ripple effect:
 
-Use CSS color property to style the ripple:

 Apply `circle` class to make the rippling effect within a circle.
 
-```html
-<paper-ripple class="circle"></paper-ripple>
