At its heart, Greenlight provides a minimalistic web-based application that allows users to: * Signup/Login with Google, Office365, OpenID Connect, or through the application itself. * Manage your account settings and user preferences. * Create and manage your own personal rooms ([BigBlueButton](https://github.com/bigbluebutton/bigbluebutton) sessions). * Invite others to your room using a simple URL. * View recordings and share them with others. Interested? Try Greenlight out on our [demo server](https://demo.bigbluebutton.org/gl)! Greenlight is also completely configurable. This means you can turn on/off features to make Greenlight fit your specific use case. For more information on Greenlight and its features, see our [documentation](http://docs.bigbluebutton.org/greenlight/gl-install.html). For a overview of how Greenlight works, checkout our Introduction to Greenlight Video: [](https://youtu.be/Hso8yLzkqj8) ## Installation on a BigBlueButton Server Greenlight is designed to work on a [BigBlueButton 2.0](https://github.com/bigbluebutton/bigbluebutton) (or later) server. For information on installing Greenlight, checkout our [Installing Greenlight on a BigBlueButton Server](http://docs.bigbluebutton.org/greenlight/gl-install.html#installing-on-a-bigbluebutton-server) documentation. ## Source Code & Contributing Greenlight is built using Ruby on Rails. Many developers already know Rails well, and we wanted to create both a full front-end to BigBlueButton but also a reference implementation of how to fully leverage the [BigBlueButton API](http://docs.bigbluebutton.org/dev/api.html). We invite you to build upon Greenlight and help make it better. See [Contributing to BigBlueButton](http://docs.bigbluebutton.org/support/faq.html#contributing-to-bigbluebutton). We invite your feedback, questions, and suggests about Greenlight too. Please post them to the [Greenlight mailing list](https://groups.google.com/forum/#!forum/bigbluebutton-greenlight). To help with organization and consistency, we have implemented a Pull Request template that must be used for all Pull Requests. This template helps ensure that the project maintainers can review all PRs in a timely manner. When creating a Pull Request, please provide as much information as possible.
