There is a SignalTap megafunction which needs to be instantiated, but everyone uses the File -> New -> SignalTap II. This file does not need to be instantiated at all, and is added under Assignments -> Settings -> SignalTap II. It is a much easier flow, allows for quick adding/removing of .stp files, and allows the user to tap nodes without manually hooking it up. There are reasons for the megafunction, but everyone uses the .stp files due to its many benefits.
