(Besides this not being "CS" as people are pointing out) This is good to give some ideas to people that like to tinker and learn by themselves, who are the people needing instructions the least. The thing is, if students don't have a step-by-step instructions they will fail and complaint, you can tell the author is not a teacher. Anecdote time: I did MS in CS in an university in the US, in one course we had to set up some XML web service in Java, the prof lifted all the instructions from official web site and gave us the slides with step-by-step commands but he missed one step, so next week nobody except me (who bothered to look up the error and RTFM) had the service set up, this was a 500 or 600 level course.
