Shaping armhole

Hi, I’m needing to shape armholes on the back of cardigan, pattern states ’ Dec st at each end of next and 6 following 4th rows, then on following 6 alt rows’
The decrease at each end…is that first and last st of row? And please could someone explain the rest in laments terms?

Yes, the first and last sts of the row. It’ll give you a neater edge if you make the dec one stitch in from the edge.
Dec on the next row, row 1 and then on rows 5,9,13,17,21,25 and rows 27,29,31,33,35,37.

Thank you so much :blush:
