Help needed with wp-list-categories

Dear Caroline,
Hoping you will help me again…

I am trying to have one circle on the home page which links to a new page with circles which display posts in a News category.

I created my own Post Format called content-quote.php in my Child Theme, displaying category ID 13 which is my News category.
Here is the code:

<?php
/**
 * BW The template used for displaying a post of categories
 *
 * @package Spun
 * @since Spun 1.0
 * Child theme Natuurschool
 */
?>

<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
	<header class="entry-header">
		<h1 class="entry-title"><?php the_title(); ?></h1>
	</header><!-- .entry-header -->

	<div class="entry-content">
		<?php wp_list_categories('orderby=name&include=13&title_li='); ?>
	</div><!-- .entry-content -->

	<footer class="entry-meta">
		<?php if ( ! post_password_required() && ( comments_open() || '0' != get_comments_number() ) ) : ?>
			<span class="comments-link">
				<a href="#comments-toggle">
					<span class="tail"></span>
					<?php echo comments_number( __( '+', 'spun' ), __( '1', 'spun' ), __( '%', 'spun' ) ); ?>
				</a>
			</span>
		<?php endif; ?>

		<?php edit_post_link( __( 'Edit', 'spun' ), '<span class="edit-link">', '</span>' ); ?>
	</footer><!-- .entry-meta -->
</article><!-- #post-<?php the_ID(); ?> -->

Then created a post called Nieuws formatted as quote (see my site http://www.schoolontwerpen.nl, it is the first circle).
Clicking on this you get a page with the word Nieuws, which leads you nicely to a page with circles displaying all the posts in the Nieuws category.

BUT I want to skip the step with the word ‘Nieuws’ and go directly from the start page to the latter displaying the circles.

Can you help me?
Which code do I need in the content-quote.php?

Thanks, Bastienne
