Shoulder shaping


The new site is awesome. However, I am unable to find anything, but we can always start over.

I am knitting a Softee Baby Hoodie

I am at the shoulder shaping. It says:

Shoulder shaping: Keeping cont of pat,
cast off 6 (7-7) sts beg next 4 rows, then
5 (6-8) sts beg following 2 rows. Cast off
rem 19 (21-23) sts.

Please help me again. I have no idea how to get this done.
Do I just cast off the first sts finish knitting the row and move to the next row?

Thank you
