+Requirements
+------------
+
+* Qt >= 5.8
+
+
+What to change
+-------------
+
+Substitute your actual username and API key in the QFlightXMLClient class.  You can also change the airlineCode in main.cpp (line 9).
+
+Running the example
+-------------------
+Open the project in Qt Creator and run the example using the IDE.
