Please help explain pattern

HI,

I am new to crocheting and just found this website. I hope this is the right place to post this qustions.

I am crocheting a ruffle for the bottom of a denim skirt.

I am completely baffled by my next line of instructions. My last stitch around the circle of the ruffle was sc and ended with joining the circle and then, ch 3.

RND 5: Sk 2 st, *make group into next st, sk 2 st, dc into next st, cont from * around to beg ch 3, join, ch 3.

If anyone can shed some light on waht I am supposed to do, I would be very grateful.
