Hello,

I think that the easiest way of doing so is to use the WordPress Recent Posts Widget and add your recent posts to your sidebar for example.

I would not really use a plugin as WordPress comes with a built-in widget to display recent posts anyway. To enable that inside your WordPress admin, visit Appearance > Widgets and add Recent Posts widget to a sidebar.

If you prefer to d this with code, you could use something like this and add it to your theme files:

<ul>
// Define your WP Query Parameters
<?php $the_query = new WP_Query( 'posts_per_page=5' ); ?>

// Prepare your WP Query
<?php while ($the_query -> have_posts()) : $the_query -> the_post(); ?>

// Get the Post Title with Hyperlink
<li><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></li>

// Get the Post Excerpt
<li><?php the_excerpt(__('(more…)')); ?></li>

// Repeat the process and reset once it hits the limit
<?php 
endwhile;
wp_reset_postdata();
?>
</ul>

Hope that this helps!
Regards,
Bobby
