+A PHP class that provides access to Ubiquiti's [**UniFi Network Application**](https://unifi-network.ui.com/) API.
 
 This class is used by our API Browser tool, which can be found
 [here](https://github.com/Art-of-WiFi/UniFi-API-browser).
 
 The package can be installed manually or by using
 composer/[packagist](https://packagist.org/packages/art-of-wifi/unifi-api-client) for

+easy inclusion in your projects. See the [installation instructions](#Installation) below for more details.
+
+
+## Why use this API client?
+
+- Easy to use: clear docs, comprehensive method coverage, and helpful examples.
+- Broad coverage: exposes many UniFi endpoints not (yet) 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.
+

-## Upgrading from a previous version
+## Upgrading from previous versions
 
-When upgrading from a version before **1.1.84**, please:
-- make sure you are using PHP **7.4** or higher
-- test the client with your code for any breaking changes; the class methods now have strict parameter type hints and 
-  response types which can break your code in certain cases where the wrong type is passed or a different response type
-  is expected back
+When upgrading from a version before **2.0.0**, please:
+- change your code to use the new Exceptions that are thrown by the class
+- test the client with your code for any breaking changes
+- make sure you are using [Composer](#composer) to install the class because the code is no longer held within a single
+  file
+- see the note [here](#looking-for-version-1xx) regarding the single file version (1.x.x) of the API client

+## Exception handling
+
+The class now throws **Exceptions** for various error conditions instead of using PHP's `trigger_error()` function. This
+allows for more granular error handling in your application code.
+
+You can also choose to catch the `UniFi_API\Exceptions\UnifiApiException` Exception to catch all Exceptions that
+might be thrown by the API Client class.
+
+Here is an example of how to catch each of the Exceptions individually:
+```php
+<?php
+/**
+ * PHP API usage example with Exception handling
+ */
+use UniFi_API\Exceptions\CurlExtensionNotLoadedException;
+use UniFi_API\Exceptions\CurlGeneralErrorException;

+/**
+ * initialize the UniFi API connection class, log in to the controller and request the alarms collection
+ * (this example assumes you have already assigned the correct values to the variables in config.php)
+ */
+try {
+    $unifi_connection = new UniFi_API\Client($controller_user, $controller_password, $controller_url, $site_id, $controller_version, true);
+    $login            = $unifi_connection->login();
+    $results          = $unifi_connection->list_alarms(); // returns a PHP array containing alarm objects
+} catch (CurlExtensionNotLoadedException $e) {
+    echo 'CurlExtensionNotLoadedException: ' . $e->getMessage(). PHP_EOL;
+} catch (InvalidBaseUrlException $e) {
+    echo 'InvalidBaseUrlException: ' . $e->getMessage(). PHP_EOL;
+} catch (InvalidSiteNameException $e) {
+    echo 'InvalidSiteNameException: ' . $e->getMessage(). PHP_EOL;
+} catch (JsonDecodeException $e) {
+    echo 'JsonDecodeException: ' . $e->getMessage(). PHP_EOL;
+} catch (LoginRequiredException $e) {
+    echo 'LoginRequiredException: ' . $e->getMessage(). PHP_EOL;
+} catch (CurlGeneralErrorException $e) {
+    echo 'CurlGeneralErrorException: ' . $e->getMessage(). PHP_EOL;
+} catch (CurlTimeoutException $e) {
+    echo 'CurlTimeoutException: ' . $e->getMessage(). PHP_EOL;
+} catch (LoginFailedException $e) {
+    echo 'LoginFailedException: ' . $e->getMessage(). PHP_EOL;
+} catch (Exception $e) {
+    /** catch any other Exceptions that might be thrown */
+    echo 'General Exception: ' . $e->getMessage(). PHP_EOL;
+}
+```
+
+Although the PHP DocBlocks for most public methods/functions contain `@throws Exception`, it is recommended to catch
+specific Exceptions that can be thrown by the API Client class to provide more detailed error messages to your
+application code.
+
+In most cases, the class will let Exceptions bubble up to the calling code, but in some cases it will catch them and
+throw a new Exception with a more specific message.
+
+The `list_alarms.php` example in the `examples/` directory is a good starting point to see how you can implement
+Exception handling.
