Yup!
Sorry, I know that's not what you wanted to read.
This may make it a bit easier, though. This is the tutorial I learned it from and it will walk you through every step as well as having the files available.

The easiest way is to download all the files first then deconstruct them as you go through the tutorial. It is definitely to your advantage to read through the entire tutorial. You will learn a lot of techniques that you can apply to many other applications as well. It is specifically for MX.
Hope that helps.
