A well-structured document is easier to read, navigate, and understand. One of the best ways to organize long documents such as reports, research papers, ebooks, manuals, or blog drafts is by adding a Table of Contents (TOC).
A Table of Contents is a list of headings in your document that allows readers to quickly jump to specific sections. Each entry links directly to a heading inside the document.
