You've gotten this far, the limit screws are child's play!
Be sure that the derailer is free to move far enough to allow the 3rd click when you upshift to the big ring.
The cage should not be free to move more than a nudge past that point.
The cable should be virtually taut when in the lowest gear before setting up the limit screws.
If the shifter has only 3 detented positions, the cable tension should first be set so that the cage almost touches the left side of the chain when the shifter and the chain are both in the middle of 3 positions.
The cage should also barely clear the right side of the chain when the shifters and chain are in the highest (hardest to pedal) positions in front and in back.
See how easy that was?
