Very true. Or things like "download and install git".

Oh wait you're on a mac you need Brew. But you're on windows? You're gonna need X. You're using linux and still don't know? (e.g. Parent installs linux on a computer for their child to learn programming on (e.g. buys them a rpi) )

Lots of "setup" stuff needs to be explained or at least guided through for a from scratch approach, but also needs to be easy to skim and skip if the person learning already knows how to do it.
