The next step

I’m afraid I don’t know how to do the next part! I’m making a ribbed lace bolero. Here’s the part I don’t understand:
row 2: p1 (p1, p1 into first yo, p1 into the back of the second yo, p1) repeat lace pattern until 1 stitch left, p1

I don’t know how to purl into my yo (or purl into back of the second) What am I missing here?

I found out this is called open chain rib stitch and found a great tutorial on ho to do it
