Sketch has a lot of very easy to use and understand documentation about their features that helped me learn it. I’ll say this: start learning about symbols early and use them to their fullest. It’s like working with components and they are very powerful. I find them to Ed e the most intuitive part of you’re coming from a UI engineering background.

I guess everyone learns differently, but for me, the best way to learn a visual gui tool is to just use it. Click around and try things and sure, sometimes you have to hunt for a feature or a quick search to figure out how to do something specific, but then the next time around, things will go quicker.
