Preface

This is where your book’s introduction goes — why you’re writing it, who it’s for, and how to read it.

This file (index.qmd) is always the first page of the book. Everything else lives in chapters/ as one file per chapter.

Write in plain Markdown. No special syntax required unless you want it (headings, bold, lists, images — all normal Markdown).
