Binding off in the round?

How do I bind off in the round. I’m knitting a sweater right now. Do I just start binding off like I would with straight needles? Passing one over the other? Do I still knit one bind off one, knit one?? I’m so new at this.

I’ve always bound off in the round using the same method as when I bind off on straight needles. (Usually just the passing one over the other method).

do I need to knit one after I bind off one?

Yes, just do it the same way you bind off flat pieces.
