Use heading 1 only for your book title on the title page.
Go through your Word document and select the text for each chapter heading and select heading 2. You don’t want these appearing in your TOC. Make sure you don’t use and headings in your copyright notices. If you want to use this heading level, select heading 3 style. On rare occasions, you might want to have sub-headings in a chapter. In most cases, you will choose heading 1 style for your book title and heading 2 style for your chapter titles.
Consistent headings are the most important step before creating references, a table of contents, or footnote insertions.
