 In order to quickly run Jitsi Meet on a machine running Docker and Docker Compose,

+* Build all images by running ``make``.
 * Create a ``.env`` file by copying and adjusting ``env.example``.

 ## 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

-* ``JVB_COMPONENT_SECRET=s3cr3t`` - Password used by the Jitsi Videobridge when connecting
-  to the XMPP server as a component.
-* ``JVB_STUN_SERVERS=stun.l.google.com:19302,stun1.l.google.com:19302,stun2.l.google.com:19302`` - STUN

 ### 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.
