# A minimal example of a signed embedding in a Django application. Run this program with:
#
#    django-admin runserver --pythonpath=. --settings=index
#
# URLs are:
# - http://localhost:8000/       : home page
#
# You will need to modify the value of `METABASE_SECRET_KEY` to make this work.
# Please see https://www.metabase.com/learn/developing-applications/advanced-metabase/embedding-charts-and-dashboards.html
# for the full tutorial.
