 # Top level Qt-Creator project file
 #
 
+# This meta-project allows qt-creator users to open
+# and configure a single project and to build all
+# required software to produce a GCS.  This includes
+# regenerating all uavobject output.
+#
+# NOTE: To use this meta-project, you MUST perform these
+# steps once for each SVN checkout:
+# - Open <top>/ground/ground.pro in qt-creator
+# - Select the "Projects" tab
+# - Under Build Settings/General heading, click "Show Details"
+# - Activate "Shadow Build"
+# - Set your Build Directory to <top>/build/ground
+#
+# <top> = The full path to the base of your svn tree which should
+# contain "flight", "ground", etc.
+
+# There is a known problem with dependencies which should be fixed.
+# Until that the following workaround for qt-creator users exists:
+#
+# - run qmake in ground directory (generated GCS Makefiles lack some
+#   uavobject targets - it is known problem);
+# - build in uavobjgenerator;
+# - build in uavobjects;
+# - run qmake in ground again (IMPORTANT - now correct GCS Makefiles
+#   will be generated).
+#
+# Now you may build GCS using "Build project 'ground'" qt-creator
+# command. If some uavobjects were added/removed, you need to repeat
+# all steps after uavobjects.pro modification.
+#
+# Please note that this workaround (and meta-project at all) is only
+# for qt-creator users. Top level Makefile handles all dependencies
+# itself and don't use ground.pro.
