Need help understanding the pattern

Hi everyone, just need a bit of help with this bit of my pattern please!

Cast on 20 sts, knit 10 rows
continue in garter stitch inc. 1 st at each end of next row and every following 6th row until there are 34 sts on needle (36 rows)
Knit 5 rows

Is the increasing part of the pattern 36 rows in total or is the pattern wrong and its 36 rows all together up to that point?!

Ta muchly!

It’s just the increasing part that’s 36 rows. So knit 20 rows and then start the increases every 6th row. You’ll finish this part of the instructions with 56 rows total.
