    This function needs to be called inside the admin_init (or init) action, otherwise it will sometimes cause a Fatal Error. 

    add_action( 'admin_init', function () {
	register_importer( 'wpdocs-import-the-things'
		'WPDocs Import the Things',
		'Lets you import those things',
		'wpdocs_the_things_importer'
	);
} );

function wpdocs_the_things_importer() {
	// echo the content of the page for when this importer is called. 
	// Just like any other admin page
}
