+# Users Authentication sample for Google App Engine
+
+This sample demonstrates how to use the [Users API][appid] on [Google App
+Engine][ae-docs].
+
+[appid]: https://cloud.google.com/appengine/docs/java/users/
+[ae-docs]: https://cloud.google.com/appengine/docs/java/
+
+## Running locally 
+This example uses the
+[Maven gcloud plugin](https://cloud.google.com/appengine/docs/java/managed-vms/maven).
+To run this sample locally:
+
+    $ mvn gcloud:run
+
+## Deploying
+In the following command, replace YOUR-PROJECT-ID with your
+[Google Cloud Project ID](https://developers.google.com/console/help/new/#projectnumber).
+
+    $ mvn gcloud:deploy -Dgcloud.gcloud_project=YOUR-PROJECT-ID
+
+## Setup
+To save your project settings so that you don't need to enter the
+`-Dgcloud.gcloud_project=YOUR-CLOUD-PROJECT-ID` parameters, you can:
+
+1. Update the <application> tag in src/main/webapp/WEB-INF/appengine-web.xml
+   with your project name.
+
+You will now be able to run
+
+    $ mvn gcloud:deploy
+
+without the need for any additional parameters.
