Understanding directions

[Marynica23]

I'd like to know if someone could help me. I am knitting a man sweater and I don't seem to understand the following part:

"Dec 1st at neck edge only in 2nd row, then 3 [4: 5: 6: 7] foll alt rows, then every foll 4th row to 22 [26: 29: 34: 37] sts, ending with RS facing for next row."

It seems a little confusing, besides it's the first time I am doing this.
Thanks in advance for any help.

"Dec 1st at neck edge only in 2nd row, then 3 [4: 5: 6: 7] foll alt rows, then every foll 4th row to 22 [26: 29: 34: 37] sts, ending with RS facing for next row."

What exactly don't you understand - what to do, or how to read this (with the number behind brackets e.d.)

If I write out what I would do for the smallest size, might that help?

Decrease 1 stitch at the neck edge (where the neck is going to be), BUT only in the 2nd row, then the 3 following alternate rows. So I'd say row 4, row 6 and row 8.
Then every following 4th row (row 12, 16, 20 e.d.) till you only have 22 stitches on your pen, ending with the right side facing for the next row.

Or are you maybe mainly wondering how to decrease?
