Are there any videos for newbs like me, on how to do this step by step, as in setting up a widget, how to set it to a button, how to get your image to appear etc.

I got some overlays and I'm missing one image and one button is dead, but I have the image.
So I'm trying to find some basic information on how to do this.

thanks.

When I get home today I will hop in discord and chat with you

This one from Jay I found really useful.  It's from a while ago and there have been updates to ATVO since then, but, it is a good place to get started.
