Need to copy "ocean implementation" from another project into my own project

Guys i m new to UE4.
Just don’t know how to implement OCEAN in UE4,

creating a small scale island,
and then water everywhere except the higher areas of that island.

or at least somebody PLEASE tell: * how to copy this ocean [link right below] into my own project:

*which files to copy and where to copy, and what else necessary other than copying files to make the ocean work.

I shall be VERY THANKFUL if somebody may make a full tutorial on creating an ocean in UE4.
