New Python users are invited to use the `Anaconda Scientific
Python
distribution <https://www.continuum.io/downloads/>`_,
which automatically installs Python and the most used libraries,
among which :py:mod:`numpy`, :py:mod:`matplotlib` and :py:mod:`netCDF4`. The
:py:mod:`mpl_toolkits.basemap`  library, which is not included
in the default Anaconda distribution, can be
installed by using the :command:`conda` command as follows:

.. code-block:: bash

   conda install basemap
