I've been looking around and I've seen many users having custom backgrounds and fonts. I really want to have a custom background so I've been looking around to see how to do it but I don't understand it at all. I want to mention that I am Autistic so I have a big struggle with understanding stuff, even if it might be simple. Are there any video tutorials around to show how to do this? I find it easier to understand things by watching how to do it.
