Still Stuck on Sweater

I’m now having problems with shaping of raglan armhole for the left front:

Instructions read: Working all raglan armhole decreases as set by back [B](I’m assuming they mean Next Row (RS): K1, sl 1, K1, psso, K to last 3 sts, K2tog, K1), [/B]dec 1 st at raglan armhole edge of next and 2 foll 4th rows, then on every foll alt row until 29 sts remain, ending with WS facing for next row.???

CAM90066 was a great at explaining the back. Any and all help is greatly appreciated!!!

Do the shaping on the armhole side only the same way as you did for the left side of the back.
