More Info
It's identical to standard NOOBS Lite except for one file (recovery.cmdline).The change to this file is simply an additional parameter called "repo".
This parameter tells NOOBS which repo file to use to find it's systems.
As you can see, I am telling NOOBS to use it's own repo file plus my additional one.
This additional repo file can be viewed here.
Enjoy!
