# How to enable commenting system in Wordpress

I am learning how to create custom Wordpress theme from this page
and everything is working except commenting system because they haven't described how to enable it (they only used <?php comment_form(); ?> to insert form into template). I can see my comment in the backend but not in the page itself (I can see a link showing 1 comment but when I click it nothing happens). Obviously I need some PHP code to show my comments but have no idea where to start! I am stuck because I just started to learn Theme Development and my PHP knowledge is limited.
Can anyone give me a suggestion or a solution for that problem? It would a mean a lot to me. Index php looks like this:

<?php get_header(); ?>

<div id="blog">
<?php if(have_posts()) : ?><?php while(have_posts()) : the_post(); ?>

<div class="post">
<h3><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h3>

<div class="entry">
<?php the_post_thumbnail(); ?>
<?php the_content(); ?>

<?php _e('Filed under&#58;'); ?> <?php the_category(', ') ?> <?php _e('by'); ?> <?php  the_author(); ?><br />
</p>

</div>
</div>

<?php endwhile; ?>

</div>

<?php endif; ?>
</div>

Thank You!!

Add in comments_template(); before your endwhile;. –  stealthyninja Nov 18 '12 at 14:52

@stealthyninja as an answer please. –  Rarst Nov 18 '12 at 15:09

Edit your comments.php template and add in
<ol class="commentlist">

This should display comments, pingbacks and trackbacks. See the Codex for wp_list_comments() for help on how to style and separate or to display just comments.
