+# Google Cloud Runtime with nyholm/psr7
+
+A runtime for [Google Cloud](https://cloud.google.com/).
+
+## Installation
+
+This runtime layer is special. It includes a `router.php` to enable the use of
+Symfony Runtime component. You need to install this package **and** the runtime you
+want to use.
+
+To use with native or Symfony application.
+
+```
+composer require runtime/google-cloud symfony/runtime
+```
+
+If you want to use it with PSR-7.
+```
+composer require runtime/google-cloud runtime/psr-nyholm-laminas
+```
+
+## Usage
+
+Define the environment variable `FUNCTION_SOURCE`.
+
+```
+# Default value
+FUNCTION_SOURCE=index.php
+```
+
+Note that Google Cloud **requires** you to have an index.php file. If you are running
+Symfony you probably want to define `FUNCTION_SOURCE=public/index.php` but you
+still need to create an `index.php`.
+
+```php
+<?php
+// index.php
+// This file is needed for google cloud
+```
+
+
