My choice of wording here was poor. What I meant to say with consider is rather to review or to evaluate. What I think happened is that I intended to write ~/ instead of /root/, but I wrote the latter erroneously because I was working with that configuration and under which they are the same. After that I continued to make errors while editing the commands between my setup and the intended target, as you may have seen that there was a mix of root and home folder being used. However, since such a blunder was already pointed out I considered going with your suggestion of guiding the user to create a new account for this and have everything be done using that. Sudo is only called where needed. I decided not to go with the approach of having a non sudo user, as this would require a lot of switching back and forth and would be probably more trouble than it is worth for most users.

I had to rework different parts to get it working again, and during this process I encountered more errors in the guide which I have corrected. Some other parts were optimized and made more consistent, e.g., now it has full paths instead of mixed use of ~/ and full paths. If you have some spare time, please take another look. Thank you.
