Downloading and installing MooTools
The first thing we need to do is download a copy of MooTools from the official MooTools website (http://www.mootools.net).
Tip
It's important to note that, at the time of this writing, http://www.mootools.com is not associated with MooTools. If you've mistakenly navigated to mootools.com, don't worry, MooTools is alive and well. A simple Google search for "mootools" should result in http://mootools.net/.
What's great about MooTools is that it's extremely modular. You can—as I fondly refer to it—roll your own version of it by downloading only the components that you're going to use. This is important if you want to keep your web applications as light as possible.
For the purpose of this book, you should download the entire MooTools Core so that we can make sure we're all in the same page.
