I was thinking about how I never "look at the language's documentation" when a book or tutorial tells me to. As a beginner/intermediate coder myself, I can't just "look at online documentation" because I don't truly understand how to use it and understand properly. Does anyone have a good resource for learning how to use documentation? I know that may sound trivial to experienced hackers, and possibly paradoxical, but I'm actually quite sincere about this request.
