metatag title and description

How can I add manual meta-tag for title and descritpion into your theme without the use of a plugin?

And I would like to remove
<meta name="generator....

and I would like to add extra info to
<meta name=’robots’ content=’max-image-preview:large’ />

noarchive, noodp, noydir

Hello,

Please add this code to the funtions.php of the child theme:

remove_action( 'wp_head', 'wp_generator' );
add_action(
	'wp_head',
	function() {
		echo '<meta name="robots" content="max-image-preview:large">';
	}
);

Best Regards
