Learn how to add a table of contents into your document in Microsoft Word. First, I show you how to add headings to your document. Text that uses a heading is automatically included as part of a table of contents. Once headings are created, we click into the References tab and insert a table of contents. I also show you how to update the page numbers and update the table of contents if you make any changes to it. As full-disclosure, I work at Microsoft as a full-time employee.
