+# Editing And Testing The Debugger Visualizer
+
+### Modify The Visualizer
+
+To modify how components are visualized in the debugger edit the file `stl\debugger\STL.natvis`. For more information on
+how to modify this file check the [natvis documentation][].
+
+### Test Your Changes
+
+You can add the natvis file to any Visual Studio C++ project if you right click your project > Add > Existing Item and
+select the STL.natvis file. After doing this you should be able to see your changes in a Visual Studio debugging
+session.
