# "#!include" directives (which insert the entries of the given .gitignore-style

# file at that point).

#

# For more information, run:

# $ gcloud topic gcloudignore

# If you would like to upload your .git directory, .gitignore file or files

# from your .gitignore file, remove the corresponding line

This repository is an example of how to run a [Django](https://www.djangoproject.com/)

app on Google App Engine Standard Environment. It uses the

[Writing your first Django app](https://docs.djangoproject.com/en/2.1/intro/tutorial01/) as the

example app to deploy.

See our [Running Django in the App Engine Standard Environment](https://cloud.google.com/python/django/appengine) tutorial for instructions for setting up and deploying this sample application.
