im new to this, how do i correctly successfully install this map

i got no clue

you need to upload the map to a file hosting service, which creates a direct link at the end of which there should be .map or use a dropbox, do not forget to correct at the end of the link dl=0 to dl=1 regarding the installation of the map on the server, ask the support service where you rent the server, because there are different conditions everywhere
