+# Kinto Example
+
+This is a basic example of running Mozillas [Kinto](https://github.com/Kinto/kinto/blob/master/docs/index.rst)
+on Managed VMs. Kinto provides a framework to sync JSON data across many devices and provide push notifications.
+Thius example uses a custom runtime to install Kinto and edit the config to run it on port 8080, which is the port that
+the base Docker image is expecting. 
+
+Since Kinto is being imported as a Python library and run as-is, no additional code is necessary.
+
+Note that this is using Kinto's basic in-memory backend. As such, the instances are tied to 1. A production
+version of Kinto would use a PostgreSQL database and Redis cluster, which would allow scaling to many instances.
+
+If you are interested in seeing this example expanded to use PostgreSQL, you can file an Issue on the Issue
+Tracker, or submit a Pull Request if you've accomplished it yourself.
