Zoom is a free client for videoconferences and meetings that we use in Agora for our online training sessions. In order to be able to join, you need to have a Zoom client installed on your device. You can get it from the following places: For Apple devices: https://apps.apple.com/us/app/zoom-cloud-meetings/id546505307 For Android: https://play.google.com/store/apps/details?id=us.zoom.videomeetings For Desktop Computers: https://support.zoom.us/hc/en-us/articles/207373866-Zoom-Installers Once installed, it's not necessary to register or sign up anywhere. Zoom meeting links usually have the format https://zoom.us/number, where the number is a 9-digit "meeting ID". If Zoom is installed, it's enough to click on the link to start the meeting. Alternatively, you can start the Zoom app manually, then tell the app that you want to Join a meeting, and enter the meeting ID manually. Here's a short video showing the process.
