 Extending OpenML-Python
 ***********************
 
-OpenML-Python provides an extension interface to connect other machine learning libraries than
-scikit-learn to OpenML. Please check the :ref:`api_extensions` and use the
-scikit-learn extension in :class:`openml.extensions.sklearn.SklearnExtension` as a starting point.

-Runtime measurement is incorporated in the OpenML sklearn-extension. Example usage and potential
-usage for Hyperparameter Optimisation can be found in the example tutorial:

+OpenML-Python provides an extension interface to connect machine learning libraries directly to
