+\chapter{Introduction}
+
+The field of Computer Science is an odd amalgamation of math, logic, statistics, philosophy, electrical engineering, psychology, and systems engineering.
+Some of your classes will be hands-on and easily applicable; others will focus on ideas and theory, leaving the application in your hands.
+
+Throughought your career as a computer scientist, computer engineer, or software engineer, you will write a lot of software.
+This book focuses on software tools that will be useful in classes, internships, and personal projects.
+Much as chemistry students are taught how to use lab equipment and mechanical engineering students learn the basics of machining,
+this book teaches the basics of tools for writing and debugging software.
+
+Each chapter of this book could be a book in itself --- our goal here is to give you an idea of what these tools are useful for
+so that you'll know where to look when you need them in the future.
+We've included links to more information on the book's topics at the end of each chapter, as well as a quick reference on how to use each tool.
+
+To get the most out of this book, you must do more than just read each chapter.
+As you read, try out the examples in the chapter.
+Once you get an example working, take it a step further --- try something that seems like it might work, or combine it with something you learned previously!
+Your learning does not end when you finish this book either.
+Keep using the tools we present; practice will improve both how quickly you can accomplish tasks and your understanding of how
+the tools, and by extension computers and software, work.
+
+A note on the copyright license of this book: copyright laws are typically used to restrict the rights of others to copy, modify, and distribute creative works.
+This book is distributed under what's known as a 'copyleft' license --- rather than restricting your rights, it ensures that you retain these rights.
+The [Creative Commons Attribution--Share Alike (CC BY-SA)](http://creativecommons.org/licenses/by-sa/4.0/) license states that you have the right to copy, modify, and distribute your modifications to this book
+as you please so long as you follow two rules:
+
+1. You have to credit the authors of the work and indicate if you have made any changes.
+2. You have to distribute your changes under the same license, giving others the same rights to your modifications as you (and they) have to the original work.
+
+We hope that learning the tools in this book make your life easier and that you have a little fun along the way.
+Happy hacking!

 In our first lab, we tried a number of different text editors.
 A couple of those (including Atom and Notepad++) included **graphical user interfaces** (GUIs).
 This means you're free to use your mouse to select text, move text, scroll through text, choose menu action, click buttons, et cetera.
