 Matplotlib interfaces
 ---------------------
 
-Matplotlib provides two different interfaces:
-
-- **Axes interface**: create a `.Figure` and one or more `~.axes.Axes` objects
-  (typically using `.pyplot.subplots`), then *explicitly* use methods on these objects
-  to add data, configure limits, set labels etc.
-- **pyplot interface**: consists of functions in the `.pyplot` module. Figure and Axes
-  are manipulated through these functions and are only *implicitly* present in the
-  background.
-
-See :ref:`api_interfaces` for a more detailed description of both and their recommended
-use cases.

         API:
 
         - `~.pyplot.subplots`: create Figure and Axes
         - :mod:`~matplotlib.axes`: add data, limits, labels etc.
         - `.Figure`: for figure-level methods
