hide a layer when revisiting the base layer

I have a layer float in on my base layer (calling it main menu) instructing users to click text boxes to see explanations for steps in a process (basically telling them how to use the slide to get info). Users will then click text boxes on the main menu to be brought to a new layer with information and a button to bring them back to the main menu when they are done. How do I prevent that instruction layer from coming up whenever the user returns to the main menu? They only need to see the instructions once and then will know what to do.
