Pattern help

#1

I am not sure what this pattern wants me to do?
It reads like this. This is a sleeve for a infants sweater I have already put the ribbing on.
Beg with a RS (k) row and working in st-st, inc 1 st at each end of 3rd row and foll 2 3rd rows. Than after I insert a pattern cont to inc as set on next 2nd row and then on every foll 3rd row until there are 56 sts.

On the 3rd row of the stockinette, inc at the beg and end of the row. Then do that on every 3rd row 2 more times. The increases will be on rows 3, 6, and 9. On the next row do the pattern row and inc again on the 2nd row after (do one row, then an inc row). Then go back to increasing on every 3rd row until you have 56 sts.

Thank You so much I have been trying and trying to figure it out. Off I go to get this sweater done for our 1st Grandbaby.
