NOTE (2025-02-08)

I've since moved the tutorial over to my website. Clarified some of the wording, added exercises at the end, added links to useful resources.

For historical reasons, I'm keeping the original text here. But if you've just stumbled upon this tutorial for the first time, you may want to check out the revised version!
