Possible to modify to use with custom post type?

I have a custom post type called “Books”. Is it possible to modify this plugin to use with that? Here’s the code I use:

	function yotuwp_books_create_posttype() {
		register_post_type( 'books',
			array(
				'labels' => array(
				'name' => __( 'Books', 'yotuwp' ),
				'singular_name' => __( 'Book', 'yotuwp' ),
				'add_new' => __('Add New', 'yotuwp'),
				'add_new_item' => __('Add New Book', 'yotuwp'),
		        'edit_item' => __('Edit Book', 'yotuwp'),
		        'new_item' => __('New Book', 'yotuwp'),
		        'view_item' => __('View Book', 'yotuwp'),
		        'search_items' => __('Search Books', 'yotuwp'),
		        'not_found' => __('No books found', 'yotuwp'),
		        'not_found_in_trash' => __('No books found in Trash', 'yotuwp'),
			),
			'public' => true,
			'has_archive' => true,
			'supports' => array('title','editor','thumbnail', 'excerpt'),
			'rewrite' => array('slug' => 'books'),
			)
		);
	}
	add_action( 'init', 'yotuwp_books_create_posttype' );
