That's correct, press the green button then press the button on your remote and it will learn that button. If you have two remotes with two buttons each you can do each remote. Then go to the other door and do the same thing with the other button. I had a tree get hit by lightning and was not so lucky, it takes out the sensors at the base of the door and usually the control logic board in the motor assembly. I did fix one by finding a blown diode.
