Deploying the application on Heroku
'''''''''''''''''''''''''''''''''''

An instance of pyAggr3g470r is running `here <https://pyaggr3g470r.herokuapp.com/>`_ .

.. code:: bash

    $ cd pyaggr3g470r
    $ heroku create
    $ heroku addons:add heroku-postgresql:dev
    $ heroku config:set HEROKU=1
    $ git push heroku master
