I think your tutorial depends too much on your editor UI. It reminds me of those tutorials (often written by Microsoft) where the IDE has changed enough to break the tutorial. This made the tutorial completely useless, because none of them would explain what I actually needed: the magic thing their IDE did in terms of essentials (text files, basic commands), so I could reproduce the effect.
This is different in the unix world, which favors tool-agnostic approaches in terms of text files & basic commands. Even as tooling & technology changes, I can usually look up the meaning of the text & those commands to update them.
That's the most important I think: not the answer itself, but where the answer comes from, so I can go back there when I need to.
