Hey Towny,
Scrolling through that guide, I can say it's very not recommended. Outdated route.
I created a spreadsheet of the recommended beginner route. https://docs.google.com/spreadsheets/d/1uZuJRYPzyQZeIl1TYu-hWPObYmq25wQXXI-JHGTwuNc/edit?usp=sharing
It avoids doing MMM 100's and the FFF framewalk which are pretty hard/inconsistent. It is about 20 seconds slower though.
You can always use the WR route if you wish.

Just have mine lol

These are all 4 major versions. Just take them all in case you need them later.
A zip file is just a compressed file. You probably have the right thing you just need to unzip the file.
