+# Google Cloud Tasks Samples
+
+## Description
+
+Al code in the snippets directory demonstrate how to invoke Cloud Tasks from PHP.
+
+`src/create_http_task.php` is a simple function to create tasks with an HTTP target.
+
+## Setup:
+
+1.  **Enable APIs** - [Enable the Cloud Tasks API](https://console.cloud.google.com/flows/enableapi?apiid=cloudtasks)
+    and create a new project or select an existing project.
+2.  **Download The Credentials** - Click "Go to credentials" after enabling the APIs. Click "New Credentials"
+    and select "Service Account Key". Create a new service account, use the JSON key type, and
+    select "Create". Once downloaded, set the environment variable `GOOGLE_APPLICATION_CREDENTIALS`
+    to the path of the JSON key that was downloaded.
+3.  **Clone the repo** and cd into this directory
+
+    ```sh
+    $ git clone https://github.com/GoogleCloudPlatform/php-docs-samples
+    $ cd php-docs-samples/tasks
+    ```
+4.  **Install dependencies** via [Composer](http://getcomposer.org/doc/00-intro.md).
+    Run `php composer.phar install` (if composer is installed locally) or `composer install`
+    (if composer is installed globally).
+5.  Create a Queue
+    To create a queue using the Cloud SDK, use the following gcloud command:
+    ```sh
+    gcloud beta tasks queues create-app-engine-queue my-appengine-queue
+    ```
+
+## Using an HTTP Target
+1. Run `php src/create_http_task.php`. The usage will print for each if no arguments are provided:
+
+    ```
+    $> php src/create_http_task.php
+    Usage: php src/create_http_task.php PROJECT_ID LOCATION_ID QUEUE_ID URL [PAYLOAD]
+    ```
+
+    where:
+    * `PROJECT_ID` is your Google Cloud Project id.
+    * `QUEUE_ID` is your queue id (ie my-appengine-queue).  
+      Queue IDs already created can be listed with `gcloud alpha tasks queues list`.
+    * `LOCATION_ID` is the location of your queue.  
+      Determine 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-pull-queue", then the
+      location is "us-central1").
+    * `URL` is the full URL to your target endpoint.
