 Utility library and code samples for working with the
 [Data Manager API](https://developers.google.com/data-manager/api) and PHP.
 
 ## Requirements
 
-* PHP 8.2+
-
-## Documentation
-
-Please refer to our [Developer
-Site](https://developers.google.com/data-manager/api/get-started/set-up-access#php)
-for documentation on how to install, configure, and use the client library.
+- PHP 8.2+
 
-## Add dependencies to your project
+## Setup instructions
 
-To use the utility library in your PHP project, install it using [Composer](https://getcomposer.org/):
+The `googleads/data-manager-util` utility library is published to
+[Packagist](https://packagist.org/packages/googleads/data-manager-util). Install
+it using [Composer](https://getcomposer.org/):
 
 ```shell
 composer require googleads/data-manager-util
 ```
 
-### Quickstart
-
-```php
-use Google\Ads\DataManagerUtil\Formatter;
-use Google\Ads\DataManagerUtil\Encoding;
-
-$formatter = new Formatter();
-
-// Format, normalize, hash (SHA-256), and hex-encode an email address:
-$email = $formatter->processEmailAddress('User.Name@gmail.com', Encoding::Hex);
-
-// Format, normalize, hash (SHA-256), and hex-encode a phone number:
-$phone = $formatter->processPhoneNumber('+1 (800) 555-0100', Encoding::Hex);
-```

-- [`src/`](src/): Source code for the `googleads/data-manager-util` library.
-  Follow the instructions above to declare a dependency on `googleads/data-manager-util`
-  in your project. Use the utilities in the library to help with common tasks like
-  formatting, normalizing, hashing, and encoding data for Data Manager API requests.

-## Usage
-
-The `samples/audiences` directory contains example scripts demonstrating how to
-ingest audience members.
-
-* `ingest_audience_members.php`: Shows how to ingest audience members without
-  encryption.
-
-Before running the samples, ensure you have set up your Google Cloud project,
-enabled the necessary APIs, and configured authentication (e.g., Application
-Default Credentials).
