function notify_admin_on_save( $post_id ) 
// Logic to send email to admin
wp_mail( 'admin@example.com', 'Post Saved', 'A new post has been saved.' );

A: The second edition covers Gutenberg basics (blocks, sidebars). For deep block development, supplement with the official “Block Editor Handbook” – but the cookbook remains excellent for backend and admin plugins.

Lefebvre’s text emphasizes that plugins interact with WordPress primarily through the Hook System. This is the foundational concept of the book.
