I am new to crocheting and I'm struggling to understand this pattern.

I'm making a little lion toy and I can't seem to understand how to do the mane part. It's the following instruction:

Rnd 10 (Mane): 3ch, working into front loop only, 3tr in first st, *miss next st, sl st into next st, miss next st, 7tr in next st; rep from * to last three sts, miss next st, sl st into next st, 3tr in first st, sl st in third ch

Simpler the explanation the more it will help! Thank you!!
