+The `core-overlay` element displays overlayed on top of other content. It starts
+out hidden and is displayed by setting its `opened` property to true.
+A `core-overlay's` opened state can be toggled by calling the `toggle`
+method.
+
+The `core-overlay` will, by default, show/hide itself when it's opened. The 
+`target` property may be set to another element to cause that element to 
+be shown when the overlay is opened.
+
+It's common to want a `core-overlay` to animate to its opened
+position. The `core-overlay` element uses a `core-transition` to handle
+animation. The default transition is `core-transition-fade` which 
+causes the overlay to fade in when displayed. See 
+<a href="../core-transition/">`core-transition`</a> for more
+information about customizing a `core-overlay's` opening animation. The
+`backdrop` property can be set to true to show a backdrop behind the overlay
+that will darken the rest of the window.
+
+An element that should close the `core-overlay` will automatically
+do so if it's given the `core-overlay-toggle` attribute. This attribute
+can be customized with the `closeAttribute` property. You can also use
+`closeSelector` if more general matching is needed.
+
+By default  `core-overlay` will close whenever the user taps outside it or
+presses the escape key. This behavior can be turned off via the
+`autoCloseDisabled` property.
+
+    <core-overlay>
+      <h2>Dialog</h2>
+      <input placeholder="say something..." autofocus>
+      <div>I agree with this wholeheartedly.</div>
+      <button core-overlay-toggle>OK</button>
+    </core-overlay>
+
+`core-overlay` will automatically size and position itself according to the 
+following rules. If the target's style.top and style.left are unset, the 
+target will be centered. The size of the target is constrained to be no larger
+than the window dimensions. The `margin` property specifies the extra amount
+of space that should be reserved around the overlay. This can be used to ensure
+that, for example, a drop shadow is always visible around the overlay.
