[Q] (SM-G313M/DS) ML roms are compatible with M/DS?

I want to go for a custom ROM on this phone, but don't know if is compatible.

I know that DS = Duos, but what means M and ML?
Also what means the HZ and HU? Is about hardware difference? Because I don't have that information.

Technical answers are totally accepted! :laugh:

Thanks everyone! :good:
