Getting start menu to work

Hi. I am in a class and still learning and I feel I missed a important point. When linking different pages (like the menu to help and back, as well as the levels), what it the proper way to do this? My gut instinct is to say External layouts, but I’m not 100% sure this is it. Here is a screenshot of where I am, yes it is the first step.

I hope you have enjoyed using the software so far.
All you need to do is use a change to scene action…
There you can fill in the scene to switch to.
I did that in this tutorial.
