I'm not sure to understand what you mean.
If you play on some server, every player who wants to place one this this blueprint should install it, no more. If you have this blueprint and another player not, that don't matter. This is not a mod, just a set of blueprints, so its use only item already in game.
He wants to know where to put the blueprint in order to use it ingame.
There's a folder called blueprint. Just download the file and copy it in that folder
