     \brief QML Types for the Qt 3D Studio Runtime module.
 
-    Qt 3D Studio provides a number of QML types to view and control the
-    presentation. These types can be imported into your application using the
-    following import statement in your .qml file:
+    The Qt 3D Studio Runtime provides a number of QML types to integrate and
+    control Qt 3D Studio presentations in Qt Quick applications. These types
+    can be imported into your application using the following import statement
+    in your \c{.qml} file:
 
     \badcode
     import QtStudio3D 2.0
     \endcode
 
+    The main type for embedding a Qt 3D Studio presentations into a Qt Quick
+    scene is \l Studio3D. Many of the other types correspond to a C++ class in
+    the API offered to non-QML based applications, providing the same level of
+    control described in \l{Qt 3D Studio Runtime C++ Classes}{the C++
+    reference}.
+
+    There are also QML types that offer functionality not available via the C++
+    classes. The \l SubPresentationSettings type allows defining \c{QML
+    sub-presentations} (live Qt Quick scenes composed into the 3D scene either
+    as Qt 3D Studio layers or as texture maps) in-line, inside a Studio3D
+    element, without having to deploy them as separate \c .qml files.
+
+    \note the \l Behavior type is to be used by \c{behavior scripts} (\c .qml
+    snippets associated with scene objects during the design phase in Qt 3D
+    Studio) and is not available in the main application code.
