Need some help to get started

I am reading the docs, looking at videos, but still dont understand HOW to begin.
Should i create the pages for the web app, and then learn how to do database?
I mean, i just want to create an MVP, but as i see this will take too much time, because i dont know what to learn in Wappler and 7 days free trial is just toooo short of a time for a new user.
