Sleeve increases?

I am knitting King Cole pattern #3545. Trying to understand the sleeves instructions which says to work 97 rows inc 1 st at each end of next and every foll 8th row, working inc sts in patt.

Not understanding exactly what to do here. Please help.
Thank you,

Vary good looking jacket.
Call the next row, row 1. Increase at each end (2sts increased per row) of rows 1, 9,17,25,33,41,49 etc until you get to to row 97.
You can increase as a knit stitch and then on the following row, incorporate that stitch into the rib pattern as either a knit or a purl.
