[Firespitter propeller plane and helicopter parts v7.1 (May 5th) for KSP 1.0]

Guys i need a bit of help. How can i install the plugin only? I mean i know the plugin is the dll so i leave the /Firespitter/plugin folder in the gamedata folder but does it require anything else? Just want to make sure. The rest of the firespitter folder content i can just delete right?
