How can I join a Zoom conference?
Normally, the host will send you an email with a link to the Zoom meeting. Inside the email, you will find a link that leads directly to the conference. Signing-in is not necessary.
You can also join by using https://hu-berlin.zoom.us/join or by entering the meeting ID in your Zoom client.
You can find an introduction on how to use the client here: https://support.zoom.us/hc/en-us/articles/201362193-Wie-nehme-ich-an-einem-Meeting-teil-
