+VarExporter Component
+=====================
+
+The VarExporter component provides various tools to deal with the internal state
+of objects:
+
+- `VarExporter::export()` allows exporting any serializable PHP data structure to
+  plain PHP code. While doing so, it preserves all the semantics associated with
+  the serialization mechanism of PHP (`__wakeup`, `__sleep`, `Serializable`,
+  `__serialize`, `__unserialize`);
+- `Instantiator::instantiate()` creates an object and sets its properties without
+  calling its constructor nor any other methods;
+- `Hydrator::hydrate()` can set the properties of an existing object;
+- `Lazy*Trait` can make a class behave as a lazy-loading ghost or virtual proxy.
+
+VarExporter::export()
+---------------------
+
+The reason to use `VarExporter::export()` *vs* `serialize()` or
+[igbinary](https://github.com/igbinary/igbinary) is performance: thanks to
+OPcache, the resulting code is significantly faster and more memory efficient
+than using `unserialize()` or `igbinary_unserialize()`.
+
+Unlike `var_export()`, this works on any serializable PHP value.
+
+It also provides a few improvements over `var_export()`/`serialize()`:
+
+ * the output is PSR-2 compatible;
+ * the output can be re-indented without messing up with `\r` or `\n` in the data;
+ * missing classes throw a `ClassNotFoundException` instead of being unserialized
+   to `PHP_Incomplete_Class` objects;
+ * references involving `SplObjectStorage`, `ArrayObject` or `ArrayIterator`
+   instances are preserved;
+ * `Reflection*`, `IteratorIterator` and `RecursiveIteratorIterator` classes
+   throw an exception when being serialized (their unserialized version is broken
+   anyway, see https://bugs.php.net/76737).
+
+Instantiator and Hydrator
+-------------------------
+
+`Instantiator::instantiate($class)` creates an object of the given class without
+calling its constructor nor any other methods.
+
+`Hydrator::hydrate()` sets the properties of an existing object, including
+private and protected ones. For example:
+
+```php
+// Sets the public or protected $object->propertyName property
+Hydrator::hydrate($object, ['propertyName' => $propertyValue]);
+
+// Sets a private property defined on its parent Bar class:
+Hydrator::hydrate($object, ["\0Bar\0privateBarProperty" => $propertyValue]);
+
+// Alternative way to set the private $object->privateBarProperty property
+Hydrator::hydrate($object, [], [
+    Bar::class => ['privateBarProperty' => $propertyValue],
+]);
+```
+
+`Lazy*Trait`
+------------
+
+The component provides two lazy-loading patterns: ghost objects and virtual
+proxies (see https://martinfowler.com/eaaCatalog/lazyLoad.html for reference).
+
+Ghost objects work only with concrete and non-internal classes. In the generic
+case, they are not compatible with using factories in their initializer.
+
+Virtual proxies work with concrete, abstract or internal classes. They provide an
+API that looks like the actual objects and forward calls to them. They can cause
+identity problems because proxies might not be seen as equivalents to the actual
+objects they proxy.
+
+Because of this identity problem, ghost objects should be preferred when
+possible. Exceptions thrown by the `ProxyHelper` class can help decide when it
+can be used or not.
+
+Ghost objects and virtual proxies both provide implementations for the
+`LazyObjectInterface` which allows resetting them to their initial state or to
+forcibly initialize them when needed. Note that resetting a ghost object skips
+its read-only properties. You should use a virtual proxy to reset read-only
+properties.
+
+### `LazyGhostTrait`
+
+By using `LazyGhostTrait` either directly in your classes or by using
+`ProxyHelper::generateLazyGhost()`, you can make their instances lazy-loadable.
+This works by creating these instances empty and by computing their state only
+when accessing a property.
+
+```php
+class FooLazyGhost extends Foo
+{
+    use LazyGhostTrait;
+}
+
+$foo = FooLazyGhost::createLazyGhost(initializer: function (Foo $instance): void {
+    // [...] Use whatever heavy logic you need here
+    // to compute the $dependencies of the $instance
+    $instance->__construct(...$dependencies);
+    // [...] Call setters, etc. if needed
+});
+
+// $foo is now a lazy-loading ghost object. The initializer will
+// be called only when and if a *property* is accessed.
+```
+
+### `LazyProxyTrait`
+
+Alternatively, `LazyProxyTrait` can be used to create virtual proxies:
+
+```php
+$proxyCode = ProxyHelper::generateLazyProxy(new ReflectionClass(Foo::class));
+// $proxyCode contains the reference to LazyProxyTrait
+// and should be dumped into a file in production envs
+eval('class FooLazyProxy'.$proxyCode);
+
+$foo = FooLazyProxy::createLazyProxy(initializer: function (): Foo {
+    // [...] Use whatever heavy logic you need here
+    // to compute the $dependencies of the $instance
+    $instance = new Foo(...$dependencies);
+    // [...] Call setters, etc. if needed
+
+    return $instance;
+});
+// $foo is now a lazy-loading virtual proxy object. The initializer will
+// be called only when and if a *method* is called.
+```
