What to do with @RenderBody()?

I have an ASP.NET MVC 3 application with JQuery UI Tabs. I have a master layout page _layout.cshtml, code below. The master _layout.cshtml requires a @RenderBody() code. Since it is required, what am I supposed to do with it. I guess where I'm going with this is I do not know if I'm doing this correctly, since I'm not using it.

Should I be and what are the problem if not ?

Thanks.

 <div class="page">
        <div id="title" style=" height:120px" >                
            <img alt="Test.com" src="/Content/images/TestLogoLeft.png" style="width:370px; float:left; margin:0px;" />
        </div>

        <div id="titleRight" style=" background-color:White; width:580px; height:120px; float:right;"></div>

        <div id="menu" style=" background-color:White; width:950px; height:400px; float:left;">

            <!-- Must have class= info to prevent flash of just content on refresh -->

<div id="main" style=" display:none">
    @RenderBody()           
</div>      

The @RenderBody call will render the content of your actual view.
You should put it wherever you want the view's content to be.
