 Customizing matplotlib
 **********************
 
+Using style sheets
+==================
+
+Style sheets provide a means to temporarily modify configuration, but in a 
+repeatable and well-ordered manner. A style sheet is a file with the same
+syntax as the :file:`matplotlibrc` file, and when applied, it will temporarily
+override the :file:`matplotlibrc`.
+
+For more information and examples, see :ref:`style-sheets`.
