+Kerberox and installbox provide a local ansible configuration space
+which can be used to install clients and/or to check/modify the local
+installation.  To do the latter, cd into 'debian-lan' and run:
+
+   'ansible-playbook --ask-become-pass -v  -i localhost, -c local  kerberox.yml'
+
+The kerberox-clients are automatically installed using the included TFTP netboot
+installer within the LAN.
