+   Caja does not allow <code>object</code> or <code>embed</code> tags
+   in HTML.  However, Shindig provides a tamed JavaScript API for
+   embedding flash on a page.  To embed a flash file, use
+   <code>Require feature="flash"</code> in your
+   ModulePrefs and <code>gadges.flash.embedFlash</code> in the body of
+   your gadget to embed flash.
+<p>
+For example, here is a YouTube video.
+<p>
+  <div id="ytapiplayer">
+    You need Flash player 10 and JavaScript enabled to view this video.
+  </div>
+  <script type="text/javascript">
+    var success = gadgets.flash.embedFlash(
+        "http://www.youtube.com/v/0AqMb-edXlc";, // Flash video
+        "ytapiplayer", // id of div to place flash object
+        "10"           // minimum version
+    );
+  </script>
+<script>gadgets.window.adjustHeight();</script>
+  ]]>
