Hi everyone where to start?

I watched some tutorials, read the docs on unity developers coming to UE, I have been trying for 3 hours to create a canvas with a simple background for a 2D top down game, still haven’t figured it out, I drag the blueprint that has the image in it into the scene and nothing happens lol. This engine is very confusing to say the least. I am more than willing to learn though, since Unity has become so greedy, I don’t want to go back.
