docs: please add more details on usage

Greetings,

since I was having issues starting a session over the MoQ Relay (Alpha), and its 14th draft endpoint, but had no issues using the cdn.moq.dev/anon endpoint, I thought I would ask here, on how to actually properly send/receive anything (even BBB) from the Cloudflare's relay endpoint?

Thank you in advance.
