 ## UniFi Controller API client class
 
-A PHP class which provides access to Ubiquiti's [**UniFi SDN Controller**](https://unifi-sdn.ui.com/) API, versions 4.X.X and 5.X.X of the UniFi SDN Controller software are supported (version 5.12.35 has been confirmed to work). It's a standalone version of the class which is used in our API browser tool which can be found [here](https://github.com/Art-of-WiFi/UniFi-API-browser).

This class is used in our API browser tool which can be found [here](https://github.com/Art-of-WiFi/UniFi-API-browser).
 
-This class can be installed manually or using composer/[packagist](https://packagist.org/packages/art-of-wifi/unifi-api-client) for easy inclusion in your projects.
+The package can be installed manually or using composer/[packagist](https://packagist.org/packages/art-of-wifi/unifi-api-client) for easy inclusion in your projects.
 
 ## Requirements
 
 - a web server with PHP and cURL modules installed (tested on Apache 2.4 with PHP Version 5.6.1 and cURL 7.42.1 and with PHP 7.2.24 and cURL 7.58.0)
 - network connectivity between this web server and the server and port (normally TCP port 8443) where the UniFi Controller is running
 
-## Installation ##
+## UniFi OS Support
+
+Support for UniFi OS-based controllers (UniFi Dream Machine Pro) has been added as of version 1.1.47. The class automatically detects UniFi OS devices and adjusts URLs and several functions/methods accordingly. If your own code applies strict validation of the URL that is passed to the constructor, please adapt your logic to allow URLs without a port suffix when dealing with a UniFi OS-based controller.
+
+Please test all methods you plan on using thoroughly before using the API Client with UniFi OS devices in a production environment.
+
+## Installation
 
 You can use [Composer](#composer), [Git](#git) or simply [Download the Release](#download-the-release) to install the API client class.
