Hi! have you checked the unity sample scene in the asset package? You can see several examples in there with different layered options and objects you can turn on and off for studying!

This sample uses the beach skin, but you can find other coast options if you have other preferences, such as the rocky water coast:
Hopefully this is clarifying enough!
