+This guides you on how to create a ISO that has Python and can run the arch installed in **unattended mode.**<br>
+We'll need to reconfigure the **releng** profile after it's been copied, to include Python etc.<br>
+To do so, we need to add some packages to `packages.x86_64` and add some commands to `customize_airootfs.sh`.
+
+    # cd ~/archlive
+    # echo -e "git\npython\npython-psutil" >> packages.x86_64
+    # cat <<EOF >> ./airootfs/root/customize_airootfs.sh
+    cd /root
+    git clone https://github.com/Torxed/archinstall.git
+    chmod +x ~/archinstall/archinstall.py
+    EOF
+    # mkdir ./airootfs/etc/skel
+    # echo '[[ -z $DISPLAY && $XDG_VTNR -eq 1 ]] && sh -c "~/archinstall/archinstall.py --default"' >> ./airootfs/etc/skel/.zprofile
+
+> Note: `~/archlive` might be different on your system, see [ArchISO#Setup](https://wiki.archlinux.org/index.php/archiso#Setup) for more info.
+
+After all those commands are done, you can go ahead and run:
+
+    # rm -v work*; ./build.sh -v
+
+Whenever this live-cd boots, from here on now - it'll run `archinstall.py` and attempt to unattendely install a default Arch Linux base OS with `base base-devel` as packages.
+Or - if successfull - a MAC-address matches a profile at [/deployments](https://github.com/Torxed/archinstall/tree/master/deployments) for the machine to be installed.
+
+> **CAUTION**: If no parameters are given, **it will devour the first disk in your system** (Usually `/dev/sda`, `/dev/nvme0n1` etc).
