Ok, I feel good that my way above is correct, you can do this an easier way by leaving the two wires intact at every point with the following directions.
Follow the direction in the app for the 2-wire setup. You will remove the red/black pair from Trans and wire cap it to one side of the wire fuse provided in the kit. Remove the red/black pair from the Front terminal and wire cap it to the other end of the wire fuse. On the setup at the doorbell you will treat the red/black as a single wire and the yellow/green as a single wire. Make sure the wire caps are secure since you will be capping 3 wires instead of 2.
