Although it is possible to read this book from begining to end, most users will want to just read the most relevant sections. Everyone should read the introduction and Chapter 2. If you have bought it for use with a particular item of hardware then next read the chapter for that hardware - you will be referred to other parts of the text for more detail should you need it. Those who are not familiar with desktop Linux should read Chapter 9 to get a feel for how to use it, before trying to install anything. Developers working with a new device or with a general interest will find the chapters on tools and techniques most useful.
