     You use wizards to create and import several types of projects and files, such
     as Qt GUI or console applications and Qt Quick applications.
-    You can also use
-    wizards to add individual files to your projects. For example, you can create
-    the following types of files:
-
-    \list
-
-        \o Qt resource files, which allow you to store binary files in the
-        application executable
-
-        \o \QD forms and Qt QML files, which specify parts of application user
-        interfaces
-
-        \o C++ class, source, or header files
-
-    \endlist
+    You can use wizards also to add individual files to your projects.
 
     The wizards prompt you to enter the settings needed
     for that particular type of project and create the necessary files for you.

+    You can create the following types of files:
+
+    \list
+
+        \o Qt resource files, which allow you to store binary files in the
+        application executable

+
+        \o Text files
+
+    \endlist
+
+    \section2 Creating C++ Classes
+
+    The \gui {C++ Class Wizard} allows you to create a C++ header and source file for
+    a new class that you can add to a C++ project. Specify the class name, base
+    class, and header and source files for the class.
+
+    The  wizard supports namespaces. To use a namespace, enter a qualified
+    class name in the \gui {Class name} field. For example:
+    MyNamespace::MySubNamespace::MyClass.
+
+    \image qtcreator-cpp-class-wizard.png "Enter Class Name dialog"
+
+    The names of the header and source file are based on the class name. To change the
+    default suffix of a file, click \gui Configure.
+
     You can create your own project and class wizards. For more information,
     see \l{Adding New Custom Wizards}.
