new mod position directly above MAIN CONTENT

how would i go about editting the index.php to add a module position directly above the main content area... ( ie where the frontpage articles are ) this would be a perfect positon to drop some banners in.... this is what i assumed i would need to add- just dont know where... your index.php is setup so much different than the joomla ja template's..

<div class="banner_wrap">
<div class="banner">
<jdoc:include type="modules" name="banner" style="xhtml" />
<div class="clr"></div>
</div>
</div>

... the width would be about 470px with variable height around 90px give or take...

thanks

You already have module position "inset" directly above the main content area.
