Where is the reference documentation?

At serverless.com, there doesn’t seem to be any meaningful reference documentation that I can find (guides, tutorials, etc seem to be there). I am reconnecting with serverless after a year or so of having been distracted by other things, but I seem to remember that there was quite some good documentation online a year ago. Has that documentation moved elsewhere?

It seems you have to search for ‘aws’ or something like that to actually find any meaningful documentation. Is that indeed the only way to get to the documentation? By already knowing what you’re looking for?
