+# Sendgrid & Google App Engine
+
+This sample application demonstrates how to use [Sendgrid with Google App Engine](https://cloud.google.com/appengine/docs/python/mail/sendgrid)
+
+Refer to the [App Engine Samples README](../../README.md) for information on how to run and deploy this sample.
+
+# Setup
+
+Before running this sample:
+
+1. You will need a [Sendgrid account](http://sendgrid.com/partner/google).
+2. Update the `SENGRID_DOMAIN_NAME` and `SENGRID_API_KEY` constants in `main.py`. You can use 
+the [Sendgrid sandbox domain](https://support.sendgrid.com/hc/en-us/articles/201995663-Safely-Test-Your-Sending-Speed).
