I am trying to integrate Google Doc. Viewer

In documentation, I found
The javascript functions do make minor use of jQuery, which can easily be added:
<script type="text/javascript" src="http://www.google.com/jsapi"></script> 

<script type="text/javascript">
google.load("jquery", "1.4");
google.setOnLoadCallback(function() {

// Place init code here instead of $(document).ready()

But , In the doc It is not mentioned that where it is to be added.

Please Do the needful and correct the document if needed.

Thanks &  Regards
