+# A Java Task Queue example for Google App Engine
+
+This sample demonstrates how to use the [TaskQueue API][taskqueue-api] on [Google App
+Engine][ae-docs].
+
+[taskqueue-api]: https://cloud.google.com/appengine/docs/java/javadoc/com/google/appengine/api/taskqueue/package-summary
+[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 appengine:devserver
+
+Go to the site `localhost:8080` to add elements to the queue.  They will appear in the log as the result of the Enqueue servlet transmitting the data to the Worker servlet.
+
+## Deploying
+In the following command, replace YOUR-PROJECT-ID with your
+[Google Cloud Project ID](https://support.google.com/cloud/answer/6158840).
+
+    $ mvn appengine:update -Dappengine.appId=YOUR-PROJECT-ID -Dappengine.version=SOME-VERSION
+
+## Setup
+To save your project settings so that you don't need to enter the
+ parameters, you can:
+
+1. Update the `<application>` tag in src/main/webapp/WEB-INF/appengine-web.xml
+   with your project name.
+
+2. Update the `<version>` tag in src/main/webapp/WEB-INF/appengine-web.xml
+   with a valid version number.
+
+
+You will now be able to run
+
+    $ mvn appengine:update
+
+without the need for any additional parameters.
