One of the easiest techniques to use to make your writing easy to follow is to use subheads in your text.
Subheads are words or phrases that stand on a line by themselves at the beginning of a section and tell the reader the main idea you will present in that section.
This is a subhead.
If you’ve ever read a textbook, you’ve seen subheads. Take a look at almost any scholarly article or nonfiction book and you’ll see them.
Any document that goes beyond a page or two will be easier to follow if it contains subheads.
