Help with instructions please

I am new to knitting and am starting on a baby afghan. I have cast on so the first row instructions says, "K1, (YO, K2 tog) across. My question is, do I knit one each time all the way across or just the first stitch only? Thanks!

Welcome!

Just knit 1 the one time and then repeat the (yo, k2tog) across the rest of the row. Only repeat what is in the ( ).
