PS4 controller layout guide?

It there a pdf or some in game help that eplains how each button/joystick on the PS4 controller is used? I am new to poE and to PlaySattion, so this would be helpful.

From what I have seen so far, there is no guide about this topic in the help section. But there is a bar in the lower part of the screen where it is always shown which buttons or stick actions you have to use to achieve what you want to do.
