I apologize if it came through as a "knee-jerk response" on my behalf, if I don't understanding the technology I work with, I look at the docs, that's why I always point others to the documentation as well. I have followed the tech guides in reference many times and I'm not in any way implying that they shouldn't be followed ad-literam, I've explained in my previous statement why I recommend the docs.
