Saving and loading from game instance?

Hey guys so basically i have my level complete and audio sliders that are functioning correctly being cast to my game instance. Now i have that all working i am wanting to save / load them upon game start up. Would i create the save in the instance and then load that on the level start up? Any help at all would be awesome sauce!
