// in this example we display a single CPT above the regular page content.
<?php query_posts( 'posts_per_page=1&post_type=customposttypename&orderby=rand'); ?>
// the posts from the CPT will rotate on page-load and display in a random order.

<?php /* The loop */ ?>
<div class="customposttypename-home">
<?php while ( have_posts() ) : the_post(); ?>
	<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
		<header class="entry-header">
			<?php if ( has_post_thumbnail() && ! post_password_required() ) : ?>
				<div class="entry-thumbnail">
					<?php the_post_thumbnail(); ?>
				</div>
			<?php endif; ?>

				<h1 class="entry-title"><?php the_title(); ?></h1>
					</header><!-- .entry-header -->

					<div class="entry-content">
						<?php the_content(); ?>
						<?php wp_link_pages( array( 'before' => '<div class="page-links"><span class="page-links-title">' . __( 'Pages:', 'twentythirteen' ) . '</span>', 'after' => '</div>', 'link_before' => '<span>', 'link_after' => '</span>' ) ); ?>
					</div><!-- .entry-content -->

				</article><!-- #post -->

<?php endwhile; /* endif; */ ?>
<?php wp_reset_query(); ?>

// and then we begin the regular loop for the page.
