The instructions were intended to be a literal "press x, press y, type z, ..."
I figured they would actually be easier to follow since they explicitly stated every character that needed typing. If you SSH into the box from a windows machine (which is how I set my RPi up), you can actually have the text file open next to the terminal window and copy/paste over. It's really, REALLY easy. On my slow DSL 1.5MB connection the hardest part is waiting for all the updates to finish. If you have a real broadband connection, it should only take a few minutes. For me, it's hours.
If there are any specific questions, I can try to answer them though I haven't used the instructions for almost a year. Like I said, I'm going to start from scratch on my RPi3 install, so I'll modify the instructions as necessary. I didn't get a chance over the weekend and now it's going to be early February before I get to it.
