   Django version 3.1.2, using settings 'githubnavigator.settings'
   Starting development server at http://127.0.0.1:8000/
   Quit the server with CONTROL-C.

After that visit http://127.0.0.1:8000/ in your browser.

.. note::

   Github has a rate limit. When the rate limit is exceed you will see an exception
   ``github.GithubException.RateLimitExceededException``. For unauthenticated requests, the rate
   limit allows for up to 60 requests per hour. To extend the limit to 5000 requests per hour you
   need to set personal access token.

   It's easy:

   - Follow this `guide <https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token>`_ to create a token.
   - Set a token to the environment variable:

   .. code-block:: bash

      export GITHUB_TOKEN=<your token>

   - Restart the app with ``python manage.py runserver``
