Another Pattern Question

#1

Cast on 9 sts.
1st row: (RS). (K1. yfwd) 8 times. K1. 17 sts.
2nd and alt rows: Purl.
3rd row: K1. (yfwd. K2) 8 times. 25 sts.
5th row: K1. (yfwd. K3) 8 times. 33 sts.
7th row: K1. (yfwd. K4) 8 times. 41 sts.
9th row: K1. (yfwd. K5) 8 times. 49 sts.
10th row: As 2nd row.
Cont in same manner, inc 8 sts on next and every following alt row to 89 (97-97-105) sts.
Place marker at end of last row.

My problem is after the 10th row…
What does that mean…
I looked up inc and on the site I got the pattern from it means to
increase 1 stitch by knitting into front and back of next stitch
but where do I do that…
I am so confused…
Reading knitting patterns is so different from crochet patterns…
I can read those easily…
But this…

After you do row 10, keep increasing 8 sts every other row, on the RS rows the same way you were on the first set of rows. The knit front and back increase you found is another way to do it, but your pattern does the increases with yarnovers, the ‘yf’. Notice it says ‘yo, k4’, then the next inc row is ‘yo, k5’? So then you would yo, k6 and yo, k7 and so on until you get to the number of stitches for your size.
