+Sample command-line programs for interacting with the Cloud Tasks API
+.
+
+App Engine queues push tasks to an App Engine HTTP target. This directory
+contains both the App Engine app to deploy, as well as the snippets to run
+locally to push tasks to it, which could also be called on App Engine.
+
+`create_app_engine_queue_task.py` is a simple command-line program to create
+tasks to be pushed to the App Engine app.
+
+`main.py` is the main App Engine app. This app serves as an endpoint to receive
+App Engine task attempts.
+
+`app.yaml` configures the App Engine app.
+
+
+## Prerequisites to run locally:
+
+Please refer to [Setting Up a Python Development Environment](https://cloud.google.com/python/setup).
+
+## Authentication
+
+To set up authentication, please refer to our
+[authentication getting started guide](https://cloud.google.com/docs/authentication/getting-started).
+
+## Creating a queue
+
+To create a queue using the Cloud SDK, use the following gcloud command:
+
+```
+gcloud beta tasks queues create-app-engine-queue my-appengine-queue
+```
+
+Note: A newly created queue will route to the default App Engine service and
+version unless configured to do otherwise.
+
+## Deploying the App Engine App
+
+Deploy the App Engine app with gcloud:
+
+* To deploy to the Standard environment:
+  ```
+  gcloud app deploy app.yaml
+  ```
+* To deploy to the Flexible environment:
+  ```
+  gcloud app deploy app.flexible.yaml
+  ```
+
+Verify the index page is serving:
+
+```
+gcloud app browse
+```
+
+The App Engine app serves as a target for the push requests. It has an
+endpoint `/example_task_handler` that reads the payload (i.e., the request body)
+of the HTTP POST request and logs it. The log output can be viewed with:
+
+```
+gcloud app logs read
+```
+
+## Run the Sample Using the Command Line
+
+Set environment variables:
+
+First, your project ID:
+
+```
+export PROJECT_ID=my-project-id
+```
+
+Then the queue ID, as specified at queue creation time. Queue IDs already
+created can be listed with `gcloud beta tasks queues list`.
+
+```
+export QUEUE_ID=my-appengine-queue
+```
+
+And finally the location ID, which can be discovered with
+`gcloud beta tasks queues describe $QUEUE_ID`, with the location embedded in
+the "name" value (for instance, if the name is
+"projects/my-project/locations/us-central1/queues/my-appengine-queue", then the
+location is "us-central1").
+
+```
+export LOCATION_ID=us-central1
+```
+
+### Using HTTP Push Queues
+
+Set an environment variable for the endpoint to your task handler. This is an
+example url to send requests to the App Engine task handler:
+```
+export URL=https://<project_id>.appspot.com/example_task_handler
+```
+
+Running the sample will create a task and send the task to the specific URL
+endpoint, with a payload specified:
+
+```
+python create_http_task.py --project=$PROJECT_ID --queue=$QUEUE_ID --location=$LOCATION_ID --url=$URL --payload=hello
+```
