+# Google Cloud Client Storage
+
+This adapter requires an instance of Google\Cloud\Storage\StorageClient that has proper access rights to the bucket you want to use.
+
+For more details see:
+http://googlecloudplatform.github.io/google-cloud-php/
+https://console.cloud.google.com/
+
+In order to get started: 
+
+1) Create a project in [Google Cloud Platform](https://console.cloud.google.com/).
+2) Create a bucket for the project in Storage.
+3) Create a Service Account in IAM & Admin section that can write access the bucket, download its key.json file.
+
+**At all times make sure you keep your key.json file private and nobody can access it from the Internet.**
+
+## Example
+
+```php
+<?php
+
+use Gaufrette\Filesystem;
+use Gaufrette\Adapter\GoogleCloudClientStorage;
+
+$storage = new StorageClient(array(
+    'projectId'     => 'your-project-id',
+    'keyFilePath'   => 'path/to/your/project/key.json'
+));
+
+# You can optionally set the directory in the bucket and the acl permissions for all uploaded files...
+# By default Cloud Storage applies the bucket's default object ACL to the object (uploaded file).
+# The example below gives read access to the uploaded files to anyone in the world
+# Note that the public URL of the file IS NOT the bucket's file url,
+# see https://cloud.google.com/storage/docs/access-public-data for details
+
+$adapter = new GoogleCloudClientStorage($storage, 'bucket_name',
+    array(
+        'directory' => 'bucket_directory',
+        'acl'       => array(
+            'allUsers' => \Google\Cloud\Storage\Acl::ROLE_READER
+        )
+    )
+);
+
+$key = 'myAmazingFile.txt';
+
+# optional
+$adapter->setMetadata($key,
+    array(
+        'FileDescription' => 'This is my file. There are many like it, but this one is mine.'
+    )
+);
+
+$filesystem = new Filesystem($adapter);
+
+$filesystem->write($key, 'Uploaded at: '.date('Y-m-d @ H:i:s'), true);
+
+```
