Install package manually? Dynamo/Revit

Hi, can someone tell me how to install a package for Dynamo manually. What do I do with the zip file and where do I put it. I use Dynamo core 2.0.38810 and Revit 2018. (I cant use the Dynamo package search.)

Kind regards, Victor

Navigate to this map and place the folder there.

This is the package folder structure

Thanks alot, works perfect.
