how to open FPS tutorial complete

Hi, im running a mac and was wondering how i open and use the FPS tutorial? i downloaded the complete version that has 2 folders inside it: Assets and Library. i tried to import assets as a package but out of the like 30 files inside there can be picked at one time.
Any help would be awesome.

EDIT1: i got the 2 packages loaded into unity but now i am wondering how to open the tutorial part were i LEARN how to make that sort of map.

You just go into Unity, and in the ‘File’ menu choose ‘Open Project’.

Then, in the bottom left of that screen, press ‘Open Other…’

Navigate to the folder which contains the Assets and Library, and click ‘Open’.
