I read it. And then comes the second part: "If you choose not to add a billing account..." If a billing account is required then the second part makes no sense, because then it would simply say the service won't work at all without it, but it talks about the monthly free credit instead. That second part is the difference between the docs for new users vs. existing users. But we'll see who's right soon. Tomorrow.
