Question what is the source of Mahdi-Rom 2.5?

Hi guys
I am a new user for Nexus 5 which is also my first Android device.
Can anyone tell me what is the source of Mahdi-Rom?
Can I flash Franco kernel for this ROM? I noticed the the Franco kernel is not compatible with CM sources. So I want to confirm the source of Mahdi-Rom in case it is from CM source.
