Why would someone who's just starting out and needs this tutorial want to use A-Text? They'll have to learn how to script sometime, and looking at one that would be super daunting to a beginner is just the trial by fire many need.
This tutorial is fine, but I'm certain that all this can be done with just XSE and editing the script. My one suggestion would be to format it a bit better so it's easier to read. Using the default text color would help for starters (pun!). It was very clear and concise though, so awesome job!
