+== Graphene Client GUI ==
+
+This is a Qt-based native GUI client for Graphene blockchains.
+
+To build this GUI, run cmake with -DBUILD_QT_GUI=ON
+
+This GUI depends on Qt 5.5 or later. If you do not have Qt 5.5 installed
+in the canonical location on your OS (or if your OS does not have a
+canonical location for libraries), you can specify the Qt path by running
+cmake with -DCMAKE_PREFIX_PATH=/path/to/Qt/5.5/gcc_64 as appropriate for
+your environment.
