Lace Pattern Question

I’m new at lace knitting and don’t understand what is meant by these instructions: K2, [p1,k1] in double yo…
I know that I knit 2 stitches but then I get lost. Please help!

You should have a double yo from the row before. You do a p1, k1 in the double yo.

OK. That makes sense. Thank you so much!
