chapters & sections

Prima facie, the creation of chapter headings is identical to standard Markdown.

# an H1 header
## an H2 header
...
###### an H6 header

But on second glance, the use of the # headers in OpenBook is markedly different.

• # headers are used to generate chapters.
• Each chapter is an HTML page on the internet.
• ## header generate sections.
• The reader can navigate to each section.
• The Table of Contents is created from the # chapters and ## sections.
• ### sub-sections and lower are disregarded for the Table of Contents. They become ordinary headers.
• When opening a book for the first time, the reader will be taken to Chapter 1.
• A preface may precede the first chapter.

Consider the following example:

preface
======

This text will appear before Chapter 1. Special thanks to my lovely wife Amber, for her patience as I buried myself in this manuscript.

## second edition
Special thanks to my lovely wife Beatrice, for her patience as I buried myself in this manuscript.

## third edition
Special thanks to my lovely wife Charlotte, for her patience as I buried myself in this manuscript.

# The First Chapter

This will be the first sentence a reader encounters.

## Section One

The reader may navigate to this section.

## Section Two

Or to this section.

# The second Chapter

The above opens a new chapter, which is situated on a separate Html page.
