Good comprehensive civ5 guide?

Veteran civ4 player here, recently bought civ5. Is there any good comprehensive civ5 guide aimed at explaining the core game mechanics of civ5?

There is no one guide fits all I'm afraid.

Would recommend visiting the war academy link houses within the strategy forum as a good starting point. Then the videos by the usual suspects - Quill, Maddjin, PrimEval etc.

I have found the following guide helpful:
