:oo: How to reverse pattern for left side

Hi, I am kinda new knitter, and i am knitting these chic gloves (with no fingers, just the thumb). There is increases, and to do the left gloves, she just says: [COLOR=“Teal”]Repeat for left glove reversing gusset increases.[/COLOR].

And I don’t know how to do that either:
[COLOR=“DarkRed”]Next row: Knit across row picking up cast on sts and knitting them together with each st.[/COLOR]

I just have absolutly not clue how to reverse that, it goes like this for the original side:

CO 20 sts.
Work 2 rows in stocking st.
Next row: K2, *yo, k2tog, repeat from * to last 2 sts, k2.
Next row: sl1, purl to end.[/COLOR][/COLOR][COLOR=“darkred”]Next row: Knit across row picking up cast on sts and knitting them together with each st.[/COLOR]Next row: sl1, purl to end.
