I would much rather learners be directed at a proper resource for doing something than trying to include all the info locally which inevitably will get out of date and become incomplete.

Is a search term really a proper resource? A chosen installation guide, preferably an official one with a stable URL (and available in the language of instruction) would be better IMHO. When the link goes dead, the learner could search based on the link title anyway.

Yes, makes sense to me, especially since it isn’t really even the purpose of the course.

I think it's a difficult thing to scale. But they're open about the results they've been able to achieve, and the challenge of scaling.

It's preparing them for the real world! It's certainly how I learnt, by breaking things at 2am and having to fix them before class at 9am.
