Besides Title, the most common field label found on a content type form is Body. Of course, this is where you place the body of your content. It’s your blog post, your how-to instructions, or maybe an event description. You know exactly what needs to be provided in this field because you are the trained author. What happens when the scenario includes many authors with varied skills?

Without clearly visible instructions for the form and the form fields, content authors can make mistakes. There are four default features in Drupal 8 that provide instructions for content authors.
