Ah, thanks for catching this!

[arctic-hen7]

Actually @Mazwak do you want to open a quick PR for this?

[Mazwak]

I can make a PR. I’m not very fluent with git and github, so I might do it badly first.

Is the link https://webassembly.org/ that you forgot ?

[arctic-hen7]

Yeah, that's the one. There's a reasonable guide in the CONTRIBUTING.md file at the root of this repo that can walk you through the basics.
