 axes, providing a simple way of displaying overviews and zoomed views of 
 data without plotting data twice.
 
+## Usage
+
+matplotview provides two methods, `view`, and `inset_zoom_axes`. The `view`
+method accepts two `Axes`, and makes the first axes a view of the second. The
+`inset_zoom_axes` method provides the same functionality as `Axes.inset_axes`,
+but the returned inset axes is configured to be a view of the parent axes.
