The idea is to show the process of a web application development. By trade I am a web applications developer (I make websites). Each scene is conceptualising the sequential steps involved. I think you'll agree that it isn't really an easy thing to put into pictures.
I'll break it down for you, although, you're absolutely right.. I shouldn't have to explain it, but I suppose if your not familiar with web tech it might be a bit of an ask. Actually, I think it's all explained in the link.. lemme check (some seconds later) yes it is, see below the video.
