+    \section1 Example Usage
+
+    A directory model that displays the contents of a default directory
+    is usually constructed with a parent object:
+
+    \snippet doc/src/snippets/shareddirmodel/main.cpp 2
+
+    A tree view can be used to display the contents of the model
+
+    \snippet doc/src/snippets/shareddirmodel/main.cpp 4
+
+    and the contents of a particular directory can be displayed by
+    setting the tree view's root index:
+
+    \snippet doc/src/snippets/shareddirmodel/main.cpp 7
+
+    The view's root index can be used to control how much of a
+    hierarchical model is displayed. QDirModel provides a convenience
+    function that returns a suitable model index for a path to a
+    directory within the model.
+
+    \section1 Caching and Performance
+
+    QFileSystemModel will not fetch any files or directories until setRootPath()
     is called.  This will prevent any unnecessary querying on the file system
     until that point such as listing the drives on Windows.
