Loadings string from datastore

Im not sure if this is the right category but does anyone know what I can do with the string on the following code with a datastore:

	datastore:SetAsync(Plr.UserId, "StringToSave")

Like how can I load the string?

RTM: DataStores

But like can you explain it shortly?

You gotta read the documentation first. The short explanation is there on that page.
