Sometimes it's one little step at a time, you figure out how to do this, and how to do that as it comes up. I had Pi problems, others had no pi problems. i can spend hours figuring out how xlights does something that I could do in LSP in a couple of minutes, and some folks can make xlights do stuff that I would spend hours doing in LSP.
Just approach it as one little learning step at a time and ask lots of questions. The facebook group is a good place too, lots more video examples there and quicker replies.
