The attention grabber you use is up to you, but here are some ideas:
ln technical writing , the introduction typically includes one or more standard subsections: abstract or summary, preface , acknowledgments, and foreword . Alternatively, the section labeled introduction itself may be a brief section found side-by-side with abstract, foreword, etc. (rather than containing them). In this case the set of sections that come before the body of the book are known as the front matter . When the book is divided into numbered chapters, by convention the introduction and any other front-matter sections are unnumbered and precede chapter 1.
