 sphinxext
 =========
 
-This directory contains copies of different sphinx extensions in use in the
-pandas documentation. These copies originate from other projects:
-
-- ``numpydoc`` - Numpy's Sphinx extensions: this can be found at its own
-  repository: https://github.com/numpy/numpydoc
-- ``ipython_directive`` and ``ipython_console_highlighting`` in the folder
-  ``ipython_sphinxext`` - Sphinx extensions from IPython: these are included
-  in IPython: https://github.com/ipython/ipython/tree/master/IPython/sphinxext
-
-.. note::
-
-    These copies are maintained at the respective projects, so fixes should,
-    to the extent possible, be pushed upstream instead of only adapting our
-    local copy to avoid divergence between the local and upstream version.
+This directory contains custom sphinx extensions in use in the pandas
+documentation.
