This is a help page in the Rich Editor Formatting section.

Dividing up the content of your article, whether it be a "First-Hand Account" or "Topic Article" into sections with headers will make it more readable to the user. It will also provide an outline view to help with navigation. For a very long article you can even create sections inside sections. The IEEE GHN will also automatically create a table of contents based on the headers that you create. To make a header, type in the section title, highlight it, and then chose one of the header levels in format box in the toolbar. Since Header 1 is reserved for the title of your article, use Header 2, Header 3, or others. See image below.
