# Time for action – adding a dedication and an appendix

Our book shall begin with a dedication. The front matter shall consist of the table of contents, lists of tables and figures, and a dedication. All the pages of the front matter shall be numbered with Roman letters. Finally, we add an appendix providing supplementary proofs which we like to present outside the main chapters:

1. Create a file dedication.tex:
\chapter{Dedication}
This book is dedicated to one of the greatest mathematicians of
all time: Carl Friedrich Gauss. Without him, this book wouldn't
have been possible.
2. Create a file proofs.tex:
\chapter{Proofs}
...
3. Extend the main file equation.tex by the highlighted lines:
\documentclass{book}
\input{preamble}
\begin{document}
\frontmatter
\include{dedication} ...
