+## overlay interaction types
+Each overlay instance has a OverlayInteraction node, which spawns the different interaction modules depending on what is defined in the OVERLAY_PROPERTIES.
+
+The modules/interaction types are:
+- Grabbable
+- Touchable
+- Clickable
+
+These modules connect signals from different places to the interaction manager (`OverlayInteraction`)
+Touchable connects collision signals to mouse inputs (potentially logic between to help prevent double presses)
+Clickable connects vr button signals to mouse inputs
+Grabbable connects vr button signals to grab logic, while telling the interaction manager to pause normal interaction
