How to connect playstation acount to epic games

Okay so have googled a dozen things but havent been able to find a clear answer. I have had rocket since 2016 from a disk and played it a ton but got a pc since 2 years ago and never really touched it. I want to pick it up again but how do i connect the 2 accounts? I have never linked a epic account when i whas on playstation.

Already thanks for helping out!
