+<p>This book documents Android 2.2 as implemented for the Google Nexus
+One phone. By releasing the sources to this book under the Creative
+Commons Attibution 3.0 License, we hope that a wide variety of OEMs
+and developers will find some or all of these chapters helpful when
+documenting their own implementations of Android 2.2. You should be
+able to remove irrelevant chapters, add your own chapters, and rewrite
+some or all of the chapters you keep, as a quicker way to document
+your Android implementation than by starting from scratch.</p>
+
+<p>Keep these points in mind when working with these files:</p>
+
+<ul>
+<li>These source files were created in Adobe Framemaker 9: you will need
+Frame and know how to use it to make use of these files. If Frame is
+not convenient for you, you can copy text from the PDF document or
+explore a utility for converting these files into other formats.</li>
+
+<li>This book uses three fonts: GeneralGG, Droid Sans, and Expert Dingbats.</li>
+
+<li>GeneralGG is available for purchase from Hoefler &amp; Frere-Jones
+(<a
+href="http://www.typography.com/home/index.php">http://www.typography.com/home/index.php</a>).
+Helveticta is a good substitute if you don't want to buy or use 
+GeneralGG, which is Google's standard sans-serif font.</li>
+
+<li>Droid Sans and Expert Dingbats are included in the fonts directory:
+they are open source fonts. Droid Sans is used for screen text. Expert
+Dingbats is used for bullets.</li>
+
+<li>All variables for the book are set in the frontmatter.fm file.</li>
+
+<li>The hidden, conditional text "HTML" is used as part of Google's
+process for converting this book into Google Help Center doc format --
+you can safely ignore it.</li>
