Need a video tutorial

Hi. I’m interested in buying this tool. But there seems to be a lack of video tutorials. I have seen some tutorials on how to install things. But I need tutorials on how to do entire projects. How am I supposed to learn how to even use this? I don’t have the time to try to read documentation and do trial and error forever. I want something like a Udemy course. Without a good course that covers everything I need to produce applications it is really hard to adopt such a software.
