Lace pattern

Hi, I’m knitting a jumper with a pattern
Commence lace pattern
Row 1 (RS) K1 (K2tog, yfwd) to last st, K1.
Row3 K1, (yfwd, sl 1, K1, psso) to last st K1
In row 1 do I just knit 1 stitch at the beginning and at the end or always knit 1 after the yfwd along the whole row?
And the same with Row 3?_

_

Repeat only the directions in parentheses. So for example, on row 1:
k1, k2tog, yfwd, k2tog, yfwd, k2tog, yfwd etc., k1.
