custom_fields.php

//activate custom fields in wordpress and name that field. Replace 'about_blurb' below with the selected name (I don't think hyphens can be used here)

<?php $meta_value = get_post_meta($post->ID, 'about_blurb', true);
  if (!empty($meta_value)) {
    echo '<p>' . $meta_value . '</p>';
  } ?>

//however, we can use the Advanced Custom Fields plugin for something much better
//this goes in our template file:

<p><?php the_field( 'about_blurb' ); ?></p>

//then, in the plugin settings, we can create custom fields that will appear on certain pages
