+## Google App Engine Managed VMs Python Custom Runtime Hello World
+
+This sample demonstrates using [Python on Google App Engine Managed VMs](https://cloud.google.com/appengine/docs/python/managed-vms/hello-world) with a custom runtime.
+
+This sample does not use the standard App Engine python runtime, but instead uses
+a custom runtime. The custom runtime ensures that any requirements defined
+in `requirements.txt` are automatically installed.
+
+### Running & deploying the sample
+
+To run the sample locally, use a virtualenv:
+
+    $ virtualenv env
+    $ source env/bin/activate.sh
+    $ pip install -r requirements.txt
+    $ python main.py
+
+To deploy the sample, use the [Google Cloud SDK](https://cloud.google.com/sdk)
+
+    $ gcloud preview app deploy app.yaml
