2. implement all the methods provided in the example.
3. register the class inside the class-main.php file.
4. dump autoload.

<?php

 * @since 1.1.0
 * @package Eightshift_Boilerplate\Columns
 */

namespace Eightshift_Boilerplate\Columns;

/**
 * Class Example_Column.
 */
class Example_Column extends Base_Post_Columns {

  /**
   * Column name constant name.
   *
   * @var string
   */
  const COLUMN_NAME = 'example';

  /**
   * Get the slug of the post type where the additional column should appear.
   *
   * @return array The name of the post type.
   */
  protected function get_post_type_slug() : array {
    return [ 'post' ];

    $columns[ static::COLUMN_NAME ] = esc_html__( 'Example', 'eightshift-boilerplate' );

    return $columns;
  }
