-# Google IOT PHP Sample Application
+# Deprecation Notice
 
-[![Open in Cloud Shell][shell_img]][shell_link]
+* <h3>Google Cloud IoT Core will be <a href="https://cloud.google.com/iot/docs/release-notes#August_16_2022">retired as of August 16, 2023</a>.</h3>
 
-[shell_img]: http://gstatic.com/cloudssh/images/open-btn.svg
-[shell_link]: https://console.cloud.google.com/cloudshell/open?git_repo=https://github.com/googlecloudplatform/php-docs-samples&page=editor&working_dir=iot
+* <h3>Hence, the samples in this directory are archived and are no longer maintained.</h3>
 
-## Description
-
-This simple command-line application demonstrates how to invoke Google
-IOT API from PHP. These samples are best seen in the context of the
-[Official API Documentation](https://cloud.google.com/iot/docs).
-
-## Build and Run
-1.  **Enable APIs** - [Enable the IOT API](
-    https://console.cloud.google.com/flows/enableapi?apiid=iot.googleapis.com)
-    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
-```
-    $ git clone https://github.com/GoogleCloudPlatform/php-docs-samples
-    $ cd php-docs-samples/iot
-```
-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.  To run the IOT Samples, run any of the files in `src/` on the CLI. Run them without arguments to print usage instructions:
-```
-$ php src/list_registries.php
-
-Usage: list_registries.php $projectId [$location='us-central1']
-
-    @param string $projectId Google Cloud project ID
-    @param string $location (Optional) Google Cloud region
-```
