How do I add a description to the node title form field? This might sound stupid, but I can't find a way to do it. I need to add a description to the node title, just like I add a description to other fields. How can I do it?
In a hook_form_alter() or hook_form_FORM_ID_alter(), add a description attribute to the node form element array:

 //Add a title field description
  $form['title']['#description'] = t('Enter your awesome title field details.');
