Write some text (such as Main Heading, Sub Heading, Third Heading on separate paragraphs) and apply the built-in Heading levels (press Ctrl+Alt+1 for Heading 1, Ctrl+Alt+2 for Heading 2, and so on) to your headings, as needed. You can delete a heading or drag it to a new location; Word will automatically renumber any affected headings:
