 ## Configuration
 
-The following variables can be set in the ``.env`` file to customize the installation:
-
-* ``CONFIG=/opt/jitsi-meet-cfg`` - Volume where the configuration of all the containers will
-  be stored.
-* ``DOCKER_HOST_ADDRESS=192.168.1.1`` - IP address of the host running Docker. See the "Running
-  on a LAN environment" section for more details.
-* ``TZ=Europe/Amsterdam`` - System time zone.
-* ``XMPP_DOMAIN=meet.jitsi`` - Domain for the XMPP server. The default works fine, since
-  the server is only accessible via the internal container network.
-* ``JVB_COMPONENT_SECRET=s3cr3t`` - Password used by the Jitsi Videobridge when connecting
-  to the XMPP server as a component.

 ### Running on a LAN environment

+If running in a LAN environment (as well as on the public Internet, via NAT) is a requirement,
 the ``DOCKER_HOST_ADDRESS`` should be set. This way, the Videobridge will advertise the IP address
 of the host running Docker instead of the internal IP address that Docker assigned it, thus making [ICE]
 succeed.
