 * Hi there
 * What can this code do when inserted in functions.php?

       function custom_rewrite_tag() {
         add_rewrite_tag('%location%', '([^&]+)');
       }
       add_action('init', 'custom_rewrite_tag', 10, 0);
       ```

 * Hi [@t-p](https://wordpress.org/support/users/t-p/)
 * Unfortunately, that article did not help me. I hope someone can provide a short
   more straightforward explanation of what that code actually does.
 * Thanks so much.
