Create a new PHP file named CourseList.php in the my/Models/Courses folder.

For example, the CourseList.php file should look like this:

<?php
namespace My\Models\GDS;

use Boostack\Models\BaseList;
use My\Models\Courses\Course;

class CourseList extends BaseList
{
    const BASE_CLASS = Course::class;

    public function __construct()
    {
        parent::init();
    }
}
?>

In this simple example, the CourseList class will inherit all methods and functionalities from the BaseList class. You can extend the CourseList class to implement new methods and logic.
