Ankestrick Diary shoulder increases

I’m not sure how to proceed with this. I have 4 markers: 1 for each shoulder and 1 for each arm. When it says knit to marker… which marker??
The set up rows are done

After the set up rows you should have 6 markers. Four were set on the RS row and 2 more on the WS row.
Ankestrick takes each of the markers as they appear on the needle. In the first shoulder increase row, you can account for the 6 markers. “Knit to marker” means knit to the next marker.
