So many tutorials will just assume everybody's system, workflow, tooling, etc. are exactly the same as theirs. How many tutorials start with just "brew install"? It wouldn't take much time at all to say "You can use Homebrew to install this - here is a link to install Homebrew for macOS and Linux"
My personal favourite is when I'm trying to debug something and the suggestions all say "sudo xyz".
Thanks but if I could have used admin permissions to dig deeper I would have done so already. A lot of us can't do that on company computers.
