I am working on a baby sweater. I can't figure out how to reverse the directions for the right front. I have done the left already

The directions say for the right front:

Shape neck: Next row: Cast off 5(6-5)sts. purl to end of row. Dec 1 st at neck edge on next and follwing atl rows 3 (4-4) times more, 12 (12-13)sts

With WS of work facing, join yarn to last 23 (25-26) sts. for right front. Work as given for left front reversing all shapings.

Is there anyone who could help me. Thank you so much

Dawn
