Arduino Mini Pin Numbering

How do I designate the Analog/Digital (AD) pins on my Arduino Mini? They are referred to as AD0 through AD3, but how do I write them into the code? Does the analogRead function know automatically that pins 0-3 refer to these four pins?

A bit confused!

Yes. Just do analogRead(0) to read from analog input 0.

Thank you.
