-## Can I use it in production?
+## Versioning ##
 
+'paperclip-aws' lets you easily use S3 file versioning if it is enabled for selected bucket.
+To find more information about versioning and how to enable it, please follow [AWS FAQs](http://aws.amazon.com/s3/faqs/#What_is_Versioning) and [AWS S3 Docs](http://docs.amazonwebservices.com/AmazonS3/latest/dev/Versioning.html).
+
+Also you can enable versioning from your Rails console by using following code:
+  
+    some_s3_attachment.data.bucket.enable_versioning
+  
+Please make sure, that user that is used to connect to S3 has enough permissions to do this, or you will get `AWS::S3::Errors::AccessDenied` error.
+  
+To get array of file versions use #versions method:
+  
+    some_s3_attachment.data.versions()
+
+## Can I use it in production? ##

 Yes, usage of **paperclip-aws** is confirmed by several rather big projects:
 
 * [www.sdelki.ru](http://www.sdelki.ru)
-* [www.lienlog.com](http://www.lienlog.com) (opens for public in December 2011)
-* [www.sharypic.com](http://www.sharypic.com) (soon)
+* [www.lienlog.com](http://www.lienlog.com)

 I hope that it is used in a lot of other projects, if you know them – let me know.
