+The Address Book Tutorial shows how to put together a simple yet
+fully-functioning GUI application. The tutorial chapters can be found in the
+Qt documentation, which can be viewed using Qt Assistant or a Web browser.
+
+The tutorial is also available online at
+
+http://doc.trolltech.com/4.4/tutorial.html
+
+All programs corresponding to the chapters in the tutorial should
+automatically be built when Qt is compiled, or will be provided as
+pre-built executables if you have obtained a binary package of Qt.
+
+If you have only compiled the Qt libraries, use the following instructions
+to build the tutorial.
+
+On Linux/Unix:
+
+Typing 'make' in this directory builds all the programs (part1/part1,
+part2/part2, part3/part3 and so on). Typing 'make' in each subdirectory
+builds just that tutorial program.
+
+On Windows:
+
+Create a single Visual Studio project for the tutorial directory in
+the usual way. You can do this by typing the following at the command
+line:
+
+qmake -tp vc
+
+You should now be able to open the project file in Visual Studio and
+build all of the tutorial programs at the same time.
+
+On Mac OS X:
+
+Create an Xcode project with the .pro file in the tutorial directory.
+You can do this by typing the following at the command line:
+
+qmake -spec macx-xcode
+
+Then open the generated Xcode project in Xcode and build it.
+
+Feel free to send comments about the tutorial to qt-bugs@trolltech.com.
