+Provisional Changes
+-------------------
+
+Provisional changes are in experimental functionality that may, or may not make
+it to future version of IPython, and which API may change without warnings.
+Activating these feature and using these API is at your own risk, and may have
+security implication for your system, especially if used with the Jupyter notebook,
+
+When running via the Jupyter notebook interfaces, or other compatible client,
+you can enable rich documentation experimental functionality:
+
+When the ``docrepr`` package is installed setting the boolean flag
+``InteractiveShell.sphinxify_docstring`` to ``True``, will process the various
+object through sphinx before displaying them (see the ``docrepr`` package
+documentation for more information.
+
+You need to also enable the IPython pager display rich HTML representation
+using the ``InteractiveShell.enable_html_pager`` boolean configuration option.
+As usual you can set these configuration options globally in your configuration
+files, alternatively you can turn them on dynamically using the following
+snippet:
+
+.. code-block:: python
+
+    ip = get_ipython()
+    ip.sphinxify_docstring = True
+    ip.enable_html_pager = True
+
+You can test the effect of various combinations of the above configuration in
+the Jupyter notebook, with things example like :
+
+.. code-block:: python
+
+    import numpy as np
+    np.histogram?
+
+This is part of an effort to make Documentation in Python richer and provide in
+the long term if possible dynamic examples that can contain math, images,
+widgets... As stated above this is nightly experimental feature with a lot of
+(fun) problem to solve. We would be happy to get your feedback and expertise on
+it.
