baby sofisticate pattern

So this my first “big” knitting project. I got the baby sophisticate pattern from ravelry knitting website. My question is are the instructions saying that I can knit this pattern on circular needles but just don’t join in the round? How do you knit with circular needles without joining?

Thanks!

You knit your first row and stop at the end of your stitches. I.E.: if you cast on 30 sts you will knit 30 sts in your first row. Then switch needles. Move the needle in your right hand to your left hand and move the needle in your left hand to your right hand. You will be knitting back and forth like you would do with straight needles.
