        Which ones?

        Manuals are like textbooks. They don't give you any real clue. They just give you enough background knowledge so that you can ask meaningful questions. They also give you just enough knowledge to be dangerous and convince others you know what you're doing.

        This is why most professions have an aprenticeship period.
