Custom Post Types

First of all you need to go to your theme config in themename/app/config.php and find $post_types variable. That is a simple array. To insert a custom post type just add a new value like:

'gallery' => array(
	'config' => array(
		'public' => true,
		'exclude_from_search' => true,
		'menu_position' => 20,
		'has_archive' => true,
		'supports' => array(
			'title',
			'editor',
			'page-attributes',
		),
		'show_in_nav_menus' => true,
	),
	'singular' => __( 'Gallery', 'textdomain' ),
	'multiple' => __( 'Galleries', 'textdomain' ),
),

The structure is the same as for register_post_type function, described in Post Types with one exception that we have added Singular and Multiple keys to generate all required labels automatically.
