It would be nice if the --host option had a clearer description. I tried to get datasette running on an AWS instance and it took a while to realize it was only listening on localhost. So I wanted to make it listen on an non-localhost interface and tried giving a couple of values to --host (a host name, then an interface name), but none of them did. In the end I read the source to see that the option is passed to uvicorn and looked at the uvicorn docs, which also didn't help. Then I searched the web for "example running datasette on a host" which led me to #514 where I saw someone using -h 0.0.0.0. I tried that and it works. That usage could be mentioned somewhere, and might save someone else some time.
