Official WASM tutorial?

I want to play around with Rust and WASM. Where do I find official & up-to-date documentation for the wasm toolchains?

2 Likes indeed is unmaintained and I should just redirect to more appropriate resources (I’m the owner of that one).

You can find the Rust+Wasm book here:
It’s maintained by the Rust+Wasm Working Group, their resources are all here:
