To add a custom post type in WordPress without using a plugin, you need to register it using the `register_post_type` function in your theme's `functions.php` file. This allows you to create a new type of content that behaves similarly to posts and pages.

<!-- BEGIN COPY / PASTE -->
    function create_custom_post_type() {
      $args = array(
        'labels' => array(
          'name' => 'Books',
          'singular_name' => 'Book'
        ),
        'public' => true,
        'has_archive' => true,
        'rewrite' => array('slug' => 'books'),
        'supports' => array('title', 'editor', 'thumbnail')
      );
      register_post_type('book', $args);
    }
    add_action('init', 'create_custom_post_type');
    <!-- END COPY / PASTE -->

Additional Comment:

Place the code snippet in your theme's `functions.php` file.
Adjust the `labels` and `supports` arrays to fit your custom post type needs.
Ensure that your theme is active, as deactivating it will disable the custom post type.
Visit the WordPress dashboard and check for the new "Books" menu item to manage your custom posts.
