I can teach you if you want but if you want to learn independently then just use these and yes there are many things to help you make Skript, its really easy and can be mastered within a year, but lets say you want something now? Well no worries within your first day you can usually get some basic stuff in and even the more advanced stuff is relatively easy but if you want/need some tutorials then here are some for you! I also recommend watching all of minehut tutorials because they are quite helpful, here are some more links for you to get started on
