BigBlueButton supports real-time sharing of audio, video, slides (with whiteboard annotations), chat, and the screen. Instructors can engage remote students with polling, emojis, multi-user whiteboards, shared notes, and breakout rooms. During the session, BigBlueButton generates analytics that are visible to moderators in the Learning Analytics Dashboard.
The latest version is BigBlueButton 2.7. You can install BigBlueButton 2.7 on Ubuntu 20.04 using [bbb-install.sh](https://github.com/bigbluebutton/bbb-install) within 30 minutes (or your money back 😉).
For full technical documentation of BigBlueButton -- including architecture, features, API, and GreenLight (the default front-end) -- see [https://docs.bigbluebutton.org/](https://docs.bigbluebutton.org/).
