On your single.php template, you need to load the category term(s), and then run a query to get other posts. In my example, I load posts from a single category. We have Wordpress SEO plugin installed which allows you to select a primary category if you decide to select several.

$related_articles = array();
$categories = get_the_category();

if($categories) {
   $category_id = $categories[0]->term_id;

   if(count($categories) > 1 && class_exists('WPSEO_Primary_Term')) {
      $primary_term = new WPSEO_Primary_Term('category', get_the_id());
      $category_id  = $primary_term->get_primary_term();

   $related_articles = get_posts(array(
      'category'    => $category_id,
      'exclude'     => $post->ID,
      'numberposts' => 3,
      'order'       => 'DESC',
      'orderby'     => 'date',
      'post_status' => 'published',
      'post_type'   => 'post'

You can then loop through the related posts, if any:

<?php if($related_articles): ?>
   <section class="related-articles">
      <?php foreach($related_articles as $post): ?>
         <?php setup_postdata($post); ?>
            <h2><?php the_title(); ?></h2>
      <?php endforeach; ?>
      <?php wp_reset_postdata(); ?>
<?php endif; ?>

Hope that helps
