Help with understanding a pattern

Please can you tell me in simple terms what the following means - I understand the decrease row but not the instructions following. For info I am doing second size - the decrease row is ‘K2, K2tog tbl, K to last 4 sts, K2 tog, K2.’

The next part is what I don’t understand:

Working all side seam decreases as set by last row, dec 1 st at each end of 4th [4th: 6th: 6th: 6th] and 0 [0: 0: 2: 3] foll 6th rows, then on 3 [3: 3: 1: 0] foll 4th rows.

I just can’t make sense of it. Thank you.

Welcome!
If you call the first written out dec row, row 1, then you would dec at each end on row 5 and then rows 9, 13 and 17.
When there’s a 0 in a pattern for your size, skip that step and go on to the next instruction.
