save prefab data

I have a project in which I put objects (prefabs) and what I would like to do is save game and when loading the object follow there with the same information.

I know that you can serialize the script data but I do not know how to localize and spawn the prefab.

I would like to know how to save the coordinates so that it appears and its script data that contains that object.

That was for unity 4 not for 5, no longer going

Why is that ?
