Como deixar apenas o resumo do post no WordPress?

Bom dia Emmanuel,

O meu tema é o indicate e no index.php está assim:

<?php global $theme; get_header(); ?>

<div id="main">

<?php $theme->hook('main_before'); ?>

<div id="content">

<?php $theme->hook('content_before'); ?>

<?php
if (have_posts()) : while (have_posts()) : the_post();
/**
* The default post formatting from the post.php template file will be used.
* If you want to customize the post formatting for your homepage:
*
* - Create a new file: post-homepage.php
* - Copy/Paste the content of post.php to post-homepage.php
* - Edit and customize the post-homepage.php file for your needs.
*
* Learn more about the get_template_part() function: http://codex.wordpress.org/Function_Reference/get_template_part
*/

get_template_part('post', 'homepage');

endwhile;

else :
get_template_part('post', 'noresults');
endif;

get_template_part('navigation');
?>

<?php $theme->hook('content_after'); ?>

</div><!-- #content -->

<?php get_sidebars(); ?>

<?php $theme->hook('main_after'); ?>

</div><!-- #main -->

<?php get_footer(); ?>

Aonde posso alterar para aparecer somente o resumo do post?
