<!DOCTYPE html>
<html class="no-js">
    <head> 
        <script src="jquery-1.10.2.min.js"></script>
            <!-- Render -->
            <script src="epub.min.js"></script> 
        <script type="text/javascript">    
        var book = ePub("Azure_Cosmos_DB_and_DocumentDB_Succinctly/");
          $(document).ready(function () {
          book.renderTo("area");
        });        
    </script>
    </head>
