Turn it counterclockwise to extend stress or clockwise to minimize pressure. Make tiny changes and take a look at the shifting by moving the chain up and down the rear cogs. Intention for easy and specific shifting in both of those directions.
This is often generally adequate to throw gear shifting out. If the equipment cable has formulated slack, you’ll want to get rid of it by pulling the inner cable as a result of at the derailleur clamp bolt (see below).
