As web developers, everything we do is mediated through a set of tools. Not just the programming languages we use, but a set of applications, libraries, commands, and what not that enable us to write and maintain our code.

* We type our code into an editor. Editors are very powerful, with all kinds of hooks for customization and automation.

* We run commands in a terminal, that uses a command shell. Command shells have all kinds of ways to automate common tasks. Many terminal programs have customization or visibility options.

* We share code using Git and GitHub. Both of these are very powerful tools, full of uncommonly used, but useful features.

* We run our code in a web browser. Modern web browsers have powerful inspection and debugging tools, as well as extension libraries.

* We use an operating system that can run other helpful applications, and which has its own opportunities for automation and customization.

There's a _lot_ of power here, but it's easy to get lost in a maze of customization for customization's sake.

This book will provide a number of genuinely useful tips and tools that will help you better manage your development environment.

I'm going to focus not just on the nuts-and-bolts of the tools and tips, but also why they are useful, and how to make them more useful.
