Quick Ribbing question

I feel so dumb because I’ve forgotten this: I’m trying to knit some basic 2x2 ribbing. I can’t remember the pattern. Do I knit into the purled stitches or purl into the purled stitches? Thanks!

Knit the knits and purl the purls.

As they face you–knit and purl as you’re looking at them, not what you did on the last row.
