"Correctly" in this case means having a receptacle hard-wired to a nearby receptacle circuit with a wiring method similar to what is in the area now, whether it be NM (Non-Metallic (Romex)), AC or MC (Armor- or Metal-clad), EMT (Electrical Metallic Tubing (thinwall conduit)), etc.
In addition, the new receptacle should be mounted in such a way that the face of the receptacle is in the living space, and not within the above-ceiling area. The box should be mounted independently of the ceiling, unless approved mounting hardware is used.
