+\section2 Building Qt Bluetooth
+
+Despite the fact that the module can be built for all Qt platforms,
+the module is not ported to all of them. Not supported platforms such as Windows desktop
+employ a fake or dummy backend which is automatically selected when the
+platform is not supported. The dummy backend reports appropriate error messages
+and values which allow the Qt Bluetooth developer to detect at runtime that the
+current platform is not supported. The dummy backend is also selected on Linux if
+BlueZ development headers are not found during build time or Qt was built without
+Qt D-Bus support.
+
+The usage of the dummy backend is highlighted via an appropriate warning while building and running.
