Super B Chain Keeper Tool TB-CH10

Could anyone explain the correct assembly for this with pictures/diagrams?

The issues I experienced are:
1. The orange wheel was clamped and not spinning
2. The alignment was wrong (the chain was jumping inwards off the jockey wheel)
3. The chain was rubbing along the top of the chain stay.

The bike It is being used on is a Cube SL Road Pro with quick release spindle.

Thank you in advance!
