Prerequisites (Things to remember before installing the CyanogenMod CM12 Nightly):

1. Users are advised to update their third party add-ons to ensure compatibility
2. The CM backupscript.sh in recovery will ignore and remove incompatible applications from your system partition (these are usually non-CM apps that users have opted to install). You must install a compatible app (or app pack) to regain that functionality
3. You can flash CM12 nightlies directly from CM11 M12 or CM 11 nightlies (no need to wipe), provided you read and followed items 1 and 2
4. Once on CM12 nightlies, you cannot downgrade back to CM11 without wiping – if you are thinking of just exploring the release, then take a backup of your existing installation if you want to go back to it.
5. Users must install Lollipop OS compatible recovery before installing the new CM12 custom ROM.
6. Make sure the device is rooted before going forward for custom ROM installation
