 ### Alternative Initialization
 
+It is possible to initialize the Options object with an associative array. The keys of the array are the option names and the values are the option values.
+
+The values can either be a single value, an array of values, or an associative array of values.
+
+- When a single value is used, it is passed as the first argument to the setter method.
+- When an array of values is used, they are destructured as passed as arguments in order to the setter method.
+- When an associative array is used, the key/value pairs are destructured and passed in as named arguments to the setter method.

 ```php
 // Create Options object with array of values
 $options = new Options([
     'width' => 300,
     'height' => 400,
-    'resizingType' => 'fill',
+    'resize' => [
