 ## UniFi API browser
+
 This tool is for browsing data that is exposed through Ubiquiti's UniFi Controller API, written in PHP, JavaScript and the [Bootstrap](http://getbootstrap.com/) CSS framework.
 
 It comes bundled with a **PHP class for access to the UniFi Controller API**, which supports [more API endpoints](https://github.com/Art-of-WiFi/UniFi-API-client#methods-and-functions-supported) than the UniFi API browser tool does.
