QtLocation was missnig basic example to show maps,
the one you can simply jump in and start hacking.

+\title Minimal Map (QML)
+\ingroup qtlocation-examples
+\brief The minimum code to display a map using Qt Quick.
+
+\image minimal_map.png
+
+\e {Minimal Map} demonstrates how to use the \l{Map} item to render a map.
+It shows the minimum amount of code needed to display the map, and can be used
+as a basis for further experimentation.
+
+\include examples-run.qdocinc
+
+\section1 C++ Code
+
+In \c main.cpp we use only the QGuiApplication and QQmlApplicationEngine
+classes.
+
+\quotefromfile minimal_map/main.cpp
+\skipto #include
+\printto main
+
+In the main function, we first instantiate a QGuiApplication object.
+Then we create a QQmlApplicationEngine and tell it to load \c main.qml
+from the \l{The Qt Resource System}{Qt Resource System}.
+
+Finally, QGuiApplication::exec() launches the main event loop.
+
+\printuntil }
+
+\section1 QML Code
+
+In \c main.qml, we import the \l {Qt Location QML Types}{QtLocation} QML module
+and its depending \l {Qt Positioning QML Types}{QtPositioning} QML module.
+Next, we create the top level window, set a sensible default size, and make
+it visible. The window will be filled by a \l [QML]{Map} item showing the map.
+
+\quotefromfile minimal_map/main.qml
+\skipto import
+\printuntil }
+\printline }
+\skipto Map
+\printuntil }
+\printline }
+
+The \l [QML]{Plugin} item is necessary to define the map provider we are
+going to use. The example can work with any of the available geo services
+plugins. However, some plugins may require additional plugin parameters
+in order to function correctly and we can use \l [QML]{PluginParameter}
+to specify them. In this example, we use the \c osm plugin, which is a
+\l {Qt Location Open Street Map Plugin} and does not require any parameters.
+
+In the \l [QML]{Map} item, we refer to the \c plugin we use and we set the \c
+center and the \c zoomLevel of the map.
+
+\section1 Requirements
+
+The example requires a working internet connection to download
+\c OpenStreetMap map tiles. An optional system proxy should be picked
+up automatically.
