How do I host a conference using Jitsi?

It's extremely simple - just visit https://jitsi.4d2.org and enter a name for your conference. You don't need to provide any credentials or personal information. Your conference will be created, and users can access your meeting using the name you provided. For example, if you created a conference called Test123, your attendees can access it using https://jitsi.4d2.org/Test123.

Jitsi supports multi-user video and/or audio conferencing via web browser or the Jitsi Meet mobile app. Download links for the mobile app for iOS and Android can be found at https://jitsi.org/downloads/. People using the mobile app will need to make sure that they set their server name to jitsi.4d2.org.
