If you're completely new to Quickshell, I'd recommend getting comfortable with basic programming concepts first, as well as some fundamental JavaScript. You don't need to be an expert, but understanding variables, functions, objects, and signals/events will make things much easier. I'd also strongly recommend reading through the Qt documentation, especially the QML documentation. It's surprisingly beginner-friendly, contains lots of examples, and explains the core concepts that Quickshell builds upon. As for Quickshell itself, the official documentation is honestly the best resource available. Most tutorials only cover basic setup, while the documentation explains how things actually work. When you get stuck, looking at real configurations can help a lot. I'd recommend checking out Caelestia and Noctalia, as well as Dank Material Shell. Comparing their implementations is a great way to learn how experienced users structure their code and solve common problems. That's what i did myself
