I feel it's where most important settings probably are to reach realistic cloud appearance but I absolutely have no idea what influence they give. It's like a lottery for me. Sometimes I am able to reach a good, naturally shaped clouds but then I rotate my camera to some degree and the clouds turns to an utter mess. There is very few information in the node reference. Whould be great to find more info, with pictures maybe for better understanding the difference all those settings create.
