+Nilmbuntu
+=========
+
 Tools to customize an Ubuntu Live CD.  Many parts of this will end up
 being version-specific.  The host machine must be running systemd,
 since the image is executed inside a systemd-nspawn container.
 
-Set up host machine, which must be running a recent systemd:
+Set up host machine:
 
-  sudo apt install squashfs-tools xorriso isolinux systemd-container iptables
+    sudo apt install squashfs-tools xorriso isolinux systemd-container iptables
-  sudo systemctl start systemd-networkd
+    sudo systemctl start systemd-networkd
 
 Choose a config:
 
-  export BUILD_CONFIG=16.04
+    export BUILD_CONFIG=20.04.1
 
 Download and extract the original ISO:
 
-  ./extractiso.sh
+    ./extractiso.sh
 
 Apply customizations, both to the outer ISO and the inner image.
 This will also run customizer-inner.sh inside a container:
 
-  ./customize.sh
+    ./customize.sh
 
 (Optional) Run and enter a shell in the container, for manual customization:
 
-  ./enter.sh
+    ./enter.sh
 
 Build the new ISO:
 
-  ./buildiso.sh
+    ./buildiso.sh
 
 Boot the ISO in QEMU with a blank HDD, to test and install:
 
-  ./run.sh -c
+    ./run.sh -c
 
 Boot QEMU with the same HDD image as above, to test an "installed" system:
 
-  ./run.sh -d
+    ./run.sh -d
 
 Remove everything but the ISOs:
 
-  ./cleanup.sh
+    ./cleanup.sh
-
-Notes:
-
-- A more proper way to build a distro from scratch would be something
-  like one of these, except that they're out of date:
