Replacing Loop-WooCommerce

Theme- Just Write

I found the documentation for <?php if ( have_posts() ) : <?php endif; ?>

Replace with
<?php woocommerce_content(); ?>

This theme does not include php if and end. The page.php code is as shown below-

<?php
/* ------------------------------------------------------------------------- *
 *	Normal page template
/* ------------------------------------------------------------------------- */

get_header(); ?>

<section class="container<?php ac_mini_disabled() ?> clearfix">

	<?php get_template_part( 'page-templates/template', 'page' ); ?>

</section><!-- END .container -->

<?php get_footer(); ?>

Where can I find <?php if ( have_posts() ) : <?php endif; ?>. Will it be located in a template? I did not want to mess around to much as I am not proficient in php.
