     1. `NormalizableInterface`
     2. `NormalizationFacadeInterface`
 
+## Quick Start
+
+#### Having:
+
+```php
+<?php
+abstract class BaseEvent
+{
+    /**
+     * @var string
+     */
+    private $id
+    /**
+     * @var DateTimeInterface
+     */
+     private $occurredAt
+
+    public function __construct()
+    {
+        $this->id = uniqid();
+        $this->occurredAt = new DateTimeImmutable();
+    }
+    
+    public  function getId(): string
+    {
+        return $this->id;
+    }
+    
+    public  function getOccurredAt(): DateTimeInterface
+    {
+        return $this->occurredAt;
+    }
+}
+
+final class FileCreatedEvent extends BaseEvent
+{
+    /**
+     * @var string
+     */
+     private $title;
+
+     public function __construct(string $title)
+     {    
+         $this->title = $title;
+     }
+}
+```
+
+#### To make **FileCreatedEvent** normalizable needed:
+
+1. `use NormalizableTrait`
+    1. by `FileCreatedEvent` to normalize **title** as normalization happens only in the frames of current visibility
+       bounds
+    2. by `BaseEvent` to normalize **occurredAt** and **id**
+2. implement `NormalizableInterface` by **BaseEvent**
+3. make properties Normalizable:
+    1. replace DateTime with **DateTimeImmutableRfc3339Normalizable** or do normalization manually
+
+```php
+abstract class BaseEvent implements \Era269\Normalizable\NormalizableInterface
+{
+    use \Era269\Normalizable\Traits\NormalizableTrait;
+    /**
+     * @var string
+     */
+    private $id;
+    /**
+     * @var DateTimeImmutableRfc3339Normalizable
+     */
+     private $occurredAt;
+
+    public function __construct()
+    {
+        $this->id = uniqid();
+        $this->occurredAt = new DateTimeImmutableRfc3339Normalizable();
+    }
+
+    public  function getId(): string
+    {
+        return $this->id;
+    }
+
+    public  function getOccurredAt(): DateTimeInterface
+    {
+        return $this->occurredAt;
+    }
+}
+
+final class FileCreatedEvent extends BaseEvent
+{
+    use \Era269\Normalizable\Traits\NormalizableTrait;
+
+    /**
+     * @var string
+     */
+    private $title;
+
+    public function __construct(string $title)
+    {
+        parent::__construct();
+        $this->title = $title;
+    }
+}
+
+$event = new FileCreatedEvent('BBB');
+print_r($event->normalize());
+```
+
+#### output:
+
+```bash
+Array
+(
+    [@type] => FileCreatedEvent
+    [id] => 6236f3ab706df
+    [occurredAt] => Array
+        (
+            [@type] => DateTimeImmutableRfc3339Normalizable
+            [dateTime] => 2022-03-20T09:28:11+00:00
+        )
+
+    [title] => BBB
+)
+```
+
+#### To customise output you need
+
+1. implement `NormalizationFacadeAwareInterface`
+2. create own Normalization strategy using the DefaultNormalizationFacade as example
+    1. use `CamelCaseToSnackCaseKeyDecorator` or own implementation to decorate keys
+    2. change the order of Normalizers, remove unneeded ar add own to influence the normalization
+
+#### Customised normalization config
+
+```php
+<?php
+$event = new FileCreatedEvent('BBB');
+$normalizationFacade = new \Era269\Normalizable\Normalizer\NormalizationFacade(
+    new \Era269\Normalizable\KeyDecorator\CamelCaseToSnackCaseKeyDecorator(),
+    [
+        new ScalarNormalizer(), // do not decorate scalar values
+        new StringableNormalizer(), // use casting on stringable
+        new NormalizableNormalizer(), // call normalize() if normalizable
+        new FailNormalizer(), // throw an exception if no supported normalizer found
+    ]
+);
+
+print_r($normalizationFacade->normalize($event));
+//or
+$event->setNormalizationFacade($normalizationFacade);
+print_r($event->normalize());
+```
+
+#### output:
+
+```bash
+Array
+(
+    [id] => 6236f74d4ca26
+    [occurred_at] => 2022-03-20T09:43:41+00:00
+    [title] => BBB
+)
+Array
+(
+    [id] => 6236f74d4ca26
+    [occurred_at] => 2022-03-20T09:43:41+00:00
+    [title] => BBB
+)
+```

+## Description:
+
+### NormalizableInterface
+
+The basic interface. Could be used separately to build fully manual normalization. How:
+
+1. any objet implements `NormalizableInterface`
+2. It is called object::normalize in `NormalizableInterface::normalize` for all required to be present in normalized
+   view objects
+
+### NormalizableTrait
+
+If it is needed to have all normalization happen automatically then `NormalizableTrait` has to be used
+with `NormalizableInterface`. In that case all objects should be supported by the `DefaultNormalizationFacade`
+
+#### DefaultNormalizationFacade
+
+Will normalize all private object properties by the next rules:
