+## PropertyDefaultsAssembler
+
+This `PropertyDefaultsAssembler` can be used together with the default `PropertyAssembler` and can be used to determine basic default values for specific properties.
+It adds default values for following scalar types: `string`, `int`, `float`, `bool`, `array`, `mixed`.
+
+Example output:
+
+```php
+    /**
+     * @var string
+     */
+    private $prop1 = '';
+```
