+Programmers shape ideas into text.
+That text gets turned into numbers and those numbers bump into other numbers
+and *make things happen*.
+To get our ideas out of our heads and the chunks of text we call "programs" we
+use text editors. Full-time programmers will easily spend thousands of hours
+of their lives interacting with their text editor doing many things:
+* Getting raw text from brains into computers.
+* Correcting mistakes in that text.
+* Restructuring the text to formulate a problem in a different way.
+* Recording how and why something was done a particular way.
+* Communicating with other programmers about all of these things.
+Vim is incredibly powerful out of the box, but it doesn't truly shine until you
+take some time to customize it for your particular work, habits, and fingers.
+This book will introduce you to Vimscript, the main programming language used to
+customize Vim. You'll be able to mold Vim around your own personal text editing
+and make the rest of your time in Vim more efficient.
+Along the way I'll also mention things that aren't strictly about Vimscript, but
+are more about learning and being more efficient in general. Learning Vimscript
+isn't going to help you much if you wind up fiddling with your editor all day
+instead of working, so you must strike a balance.
+Each chapter of the book focuses on a single topic. They're short but packed
+with information, so don't just skim them. If you really want to learn the most
+you can from this book, you need to *type in* all of the commands.
+You may already be an experienced programmer who's used to reading code and
+understanding it straight away. If so: it doesn't matter. Learning Vim and
+Vimscript is a different experience from learning a normal programming language.
+**Type. In. The. Exercises.**
+First, Vimscript is old and has a lot of dusty corners and twisty hallways. One
+configuration option can change how the entire language works. By typing
+*every* command in *every* exercise you'll discover problems with your Vim build
+or configuration on the simpler commands, which will be easier to diagnose and
+Second, Vimscript *is* Vim. To save a file in Vim, you type `:write` (or `:w`
+for short) and press return. To save a file in a Vimscript, you use `write`.
+Mastering a text editor means developing muscle memory, which you simply can't
