Live translation room
Everyone speaks their own language and hears everyone else in theirs, live, in one room.
Joining?
There is nothing to do here. Point your phone's camera at the QR code the organiser is showing, pick the language you speak and the language you want to hear, and allow the microphone. You need no account, no app and no password.
Running the room?
The console is at /admin. Create the room there; it shows the QR code for everyone else, and it takes part in the conversation itself.
On a deployment that sets ADMIN_PASSWORD, /admin asks for it first. See docs/DEPLOYMENT.md.
