Further down are examples and cheat sheets on how to create different live ISO's.
 
+## Unattended installation based on MAC address
+
+Archinstall comes with a [unattended](examples/unattended.py) example which will look for a matching profile for the machine it is being run on, based on any local MAC address. For instance, if the machine that [unattended](examples/unattended.py) is run on has the MAC address `52:54:00:12:34:56` it will look for a profile called [profiles/52-54-00-12-34-56.py](profiles/52-54-00-12-34-56.py). If it's found, the unattended installation will commence and source that profile as it's installation proceedure.
