Reading documentation is the best way to learn a tool in my experience, however I often struggle to focus on reading, and when I do I find YouTube videos explaining the tools to be invaluable. Combining both, and doing a bit of experimentation on your own I think is the most productive way to learn things. AI is great for specific niche questions that you haven't been able to solve, but make sure not to get dragged into the vibe-coding pit.

Getting started on a project using a new technology can be very daunting. I find the best way to start is by watching a tutorial, following along initially, and once the tutorial is done, do it again without help. You'll learn what you don't understand, and then you can go back and read the documentation or rewatch the video to better understand the parts you don't get.
It's a slower process that AI, but it means you'll actually learn and understand what you're doing, which is far more important than speed.

Good luck.
