Describe the problem

There are a lot of guides and articles, but no actual documentation of the API interface. F.ex: What are the arguments of getTranslations?

I agree that this would be helpful, yes! This will require some thought about how to separate the pages that are rather guides and the ones with API documentation. I think https://react.dev/ does a pretty decent job with this.
