[[PreForeword]]

=== Foreword

Wireshark is one of those programs that many network managers would love to be
able to use, but they are often prevented from getting what they would like from
Wireshark because of the lack of documentation.

This document is part of an effort by the Wireshark team to improve the
usability of Wireshark.

We hope that you find it useful and look forward to your comments.

[[PreAudience]]

=== Who should read this document?

The intended audience of this book is anyone using Wireshark.

This book will explain all the basics and also some of the advanced features
that Wireshark provides. As Wireshark has become a very complex program since
the early days, not every feature of Wireshark may be explained in this book.

This book is not intended to explain network sniffing in general and it
will not provide details about specific network protocols. A lot of
useful information regarding these topics can be found at the Wireshark
Wiki at link:{wireshark-wiki-url}[].

By reading this book, you will learn how to install Wireshark, how to use the
basic elements of the graphical user interface (such as the menu) and what's
behind some of the advanced features that are not always obvious at first sight.
It will hopefully guide you around some common problems that frequently appear
for new (and sometimes even advanced) users of Wireshark.
