Either way, these two docs [0,1] (not just those particular pages) could really use some clarifications. I had trouble working my way through either of them and they seemed to be giving conflicting information at times.
Granted, I have no significant experience with .NET or Mono. I was able to install Mono once on Ubuntu. But I gave up after trying to install .NET Core on Ubuntu (and FreeBSD) more recently - a week ago. Sorry, I can't provide more substantial criticism right now.
I guess the forums[2] would be the best place to bring these issues up in the future (with more information)?
