Is Content cooking type in UDK doc still work?

UE4 doc about content cooking is very little, are concepts in UDK docs still the same? UDK | ContentCooking

,

UDK is different than UE4. I would not use the documentation from UDK for UE4. If you’re looking for something similar to UDK for cooking your project, check out [Unreal Frontend][1].

Good luck!
