Organize posts by Category in Home Page?

Hi, I'm currently working on a custom theme and was wondering how I can create a home page with distinct category sections (simply separating posts by category) like in this theme: http://demo.wpzoom.com/?theme=magnific

Is there a specific tidbit of PHP I have to include in the homepage, or is there some call I have to enter? I'd just like to separate the posts by category. From there, I think I can tinker my way around and create the rest of the theme. Any input would be greatly appreciated

 

Assuming you're using Wordpress? You need to add a post query before your loop like so:

<!-- POST QUERY -->
<?php query_posts($query_string . '&cat=13'); ?> 
<!-- change cat=13 to the category to be displayed -->

<!-- THE LOOP -->
<?php if (have_posts()) : ?>
<?php while (have_posts()) : the_post(); ?>
<!-- YOUR STUFF -->         
<?php endwhile; else: ?>
<?php endif; ?>
<!-- LOOP ENDS -->
