The C module api docs are all on the website, via the valkey-doc repo.

@zuiderkwast That's fair - I think I was more talking about the idea that there should be a module list as there is a client list.

[zuiderkwast]

I can read above "module SDKs". That's not the same as a list of modules. Both are good to add though.

Ahh! I think I made this issue in response to a conversation at the conference and I didn't quite get it.

But yeah, I agree, we need to get the Rust Module SDKs up somewhere aside from GitHub and we need to have a place for modules. I'll split it out.
