 This extension provides [Flysystem](http://flysystem.thephpleague.com/) integration for the Yii framework.
 [Flysystem](http://flysystem.thephpleague.com/) is a filesystem abstraction which allows you to easily swap out a local filesystem for a remote one.
 
+**This version requires Flysystem 3.x and PHP 8.1+**
+
 ## Installation
 
 The preferred way to install this extension is through [composer](http://getcomposer.org/download/).
