+Jitsi auto install
+==================
+
+Jitsi requires some host-specific configuration during installation and
+according to their forum it is easier to re-install the package with right
+configuration than to edit an existing installation.
+At least this goes for the automatic installation using the debian package.
+With the manual installation, we'd have all freedom. But let's stick to the
+deb-installation.
+
+This means, we will use a per-host script that is executed on the host
+during startup.
+
+For this, we will create a systemd unit that is execute in case a specific
+folder (`/etc/jitsi`) does not exist. This unit will then perform an
+unattended install of Jitsi.
+
+To achieve this, the systemd unit has to be installed into the QEMU image
+before boot. We achieve this with `guestmount`. All steps to change the image
+are given in `modify-image.sh`.
+
+As of the time of writing this guide, there is no functionality inside
+`aetherscale` to define ones own user script to execute during host boot.
+Since the environment variable `JITSI_HOSTNAME` has to be set differently
+for each VM it also does not work to prepare an image with these steps. Thus,
+at the time of writing this can only serve as an example what could be possible
+with a few modifications.
