How to allow people register my Peertube node

Where is the configuration that allows a visitor to create an account and upload files?
Can registration be limited to some mail domain? (example: * )

You can enable registrations in the admin panel.

No, PeerTube doesn’t have that functionality at its core. However plugins can develop that functionality.

Okay, sorry, I didn’t find the path before:
Administration -> Configuration -> New users -> Enable registration (checkbox)
