+Prerequisite: PYTHON:
+~~~~~~~~~~~~~~~~~~~~~~
+You will need python installed to run bifacial_radiance. We suggest using the latest release of `Anaconda with Python 3.7 <https://www.anaconda.com/distribution/>`_ (Python 2.7 is still supported but in the process of being deprecated). Anaconda will install ``Spyder`` to work with the python scripts, and also it will install ``Jupyter``, which is the tool we use for our `tutorial trainings <https://github.com/NREL/bifacial_radiance/tree/master/docs/tutorials>`_
