table of contents

When a document is long (more than 10 paragraphs), you should provide a table of contents (TOC). Generally it should be placed between the summary and the main body of text, and should be generated from subheads within the documents. In long documents, you should use subheads approximately every five paragraphs. The TOC should be linked to its corresponding subhead within the document.
