Boolos "the logic of provability" says that PA can be axiomised

zero and the successor functions as primitive symbols.
Unfortunedly he doesn't tell how to do so.
Can somebody enlighten me here?
I would think you could replace the two primitive symbols 0 and s with

provide the context of what he said? That might give us some clues.
