Picot cast on

I have a pattern I want to do that calls for the picot cast on. Does anyone know how to do that? I googled it but couldn’t really find any helpful info. thank you everyone.

Use the knitted cast on and *CO 5 sts, BO 2 sts, slip st on right needle back to left needle, repeat from * til you have the number of st needed.

Does it just say a picot cast on? Because there is another one where you knit X rows, do a row of K2tog, YOs, knit an equal amt of the X rows and then join the cast on edge with the working stitches.

If it just says picot cast on, I’d do the first one mentioned.

thank you so much for your quick reply. I couldn’t find any info about picot cast on anywhere.
