Provide documentation about adding support for more languages!
Hi, Thanks for WASM-4! ❤️ 

In fact WebAssembly have been supported by wide list of languages which can be found here: https://github.com/appcypher/awesome-wasm-langs

The only problem here that if dev would like to add support or definitions for a language from the list, By myself looked into docs but this isn't mentioned...

Is there a guide or someway to add more languages?
