+## Why use this API client?
+
+- Easy to use: clear docs, comprehensive method coverage, and helpful examples.
+- Broad coverage: exposes many UniFi endpoints not available in the official APIs.
+- Composer-friendly: installable via [Composer](https://getcomposer.org) and works with modern PHP projects.
+- Lightweight and dependency-free: no external libraries required; uses cURL.
+- Secure: communicates over TLS and supports optional SSL certificate validation.
+- Flexible and extensible: includes `custom_api_request()` for calling any API endpoint.
+- Robust error handling: throws named Exceptions for precise try/catch handling.
+- Actively maintained: regular updates and compatibility with recent UniFi versions.
