2. Then, over in the Inspector panel, rename it to ARController.
3. Click Add Component, find Scripts in the list, and add the AR Controller component to this object.

This object will be the base of all the interactions with ARToolkit. A fully expanded view of this component is shown here:

When you imported the package, it should have automatically added layers named AR background, AR background 2, and AR foreground.

1. Click the Layer selection to make sure they're there, and add them, if necessary, to the layers list and to the AR Controller component Layer option:
