+The VarDumper Component
+=======================
+
+    The VarDumper component provides mechanisms for walking through any arbitrary PHP variable.
+    Built on top, it provides a better ``dump()`` function, that you can use instead of ``var_dump()``,
+    *better* meaning:
+
+    - per object and resource types specialized view to e.g. filter out Doctrine noise
+      while dumping a single proxy entity, or get more insight on opened files with
+      ``stream_get_meta_data()``.
+    - configurable output format: HTML, command line with colors or JSON.
+    - ability to dump internal references, either soft ones (objects or resources)
+      or hard ones (``=&`` on arrays or objects properties). Repeated occurrences of
+      the same object/array/resource won't appear again and again anymore. Moreover,
+      you'll be able to inspected the reference structure of your data.
+    - ability to operate in the context of an output buffering handler.
+
+.. versionadded:: 2.6
+    The VarDumper component was introduced in Symfony 2.6.
+
+Installation
+------------
+
+You can install the component in 2 different ways:
+
+* :doc:`Install it via Composer </components/using_components>` (``symfony/var-dumper`` on `Packagist`_);
+* Use the official Git repository (https://github.com/symfony/VarDumper).
+
+The dump() function
+-------------------
+
+The VarDumper component creates a global ``dump()`` function that is auto-configured out of the box:
+HTML or CLI output is automatically selected based on the current PHP SAPI.
+
+``dump()`` is just a thin wrapper for ``\Symfony\Component\VarDumper\VarDumper::dump()`` so can you also use it directly.
+You can change the behavior of this function by calling ``\Symfony\Component\VarDumper\VarDumper::setHandler($callable)``:
+calls to ``dump()`` will then be forwarded to the ``$callable`` given as first argument.
+
+Advanced usage
+--------------
+
+Cloners
+~~~~~~~
+
+A cloner is used to create an intermediate representation of any PHP variable.
+Its output is a Data object that wraps this representation.
+A cloner also applies limits when creating the representation, so that the corresponding
+Data object could represent only a subset of the cloned variable.
+
+You can create a Data object this way::
+
+    $cloner = new PhpCloner();
+    $data = $cloner->cloneVar($myVar);
+
+Before cloning, you can configure the limits with::
+
+    $cloner->setMaxItems($number);
+    $cloner->setMaxString($number);
+
+These limits will be applied when calling ``->cloneVar()`` afterwise.
+
+Casters
+~~~~~~~
+
+Objects and resources nested in a PHP variable are casted to arrays in the intermediate Data representation.
+You can tweak the array representation for each object/resource by hooking a Caster into this process.
+The component already has a many casters for base PHP classes and other common classes.
+
+If you want to build your how Caster, you can register one before cloning a PHP variable.
+Casters are registered using either a Cloner's constructor or its ``addCasters()`` method::
+
+    $myCasters = array(...);
+    $cloner = new PhpCloner($myCasters);
+
+or::
+
+    $cloner->addCasters($myCasters);
+
+The provided ``$myCasters`` argument is an array that maps a class, an interface or a resource type to a callable::
+
+    $myCasters = array(
+        'FooClass' => $myFooClassCallableCaster,
+        ':bar resource' => $myBarResourceCallableCaster,
+    );
+
+As you can notice, resource types are prefixed by a ``:`` to prevent colliding with a class name.
+
+Because an object has one main class and potentially many parent classes or interfaces,
+many casters can be applied to one object. In this case, casters are called one after the other,
+starting from casters bound to the interfaces, the parents classes and then the main class.
+Several casters can also be registered for the same resource type/class/interface.
+They are called in registration order.
+
+Casters are responsible for returning the properties of the object or resource being cloned in an array.
+They are callables that accept four arguments::
+
+    /**
+     * A caster not doing anything.
+     *
+     * @param object|resource $object   The object or resource being casted.
+     * @param array           $array    An array modelled for objects after PHP's native `(array)` cast operator.
+     * @param Stub            $stub     A Cloner\Stub object representing the main properties of $object (class, type, etc.).
+     * @param bool            $isNested True/false when the caster is called nested is a structure or not.
+     *
+     * @return array The properties of $object casted in an array.
+     */
+    function myCaster($origValue, $array, $stub, $isNested)
+    {
+        // Here, populate/alter $array to your needs.
+
+        return $array;
+    }
+
+For objects, the ``$array`` parameter comes pre-populated with PHP's native ``(array)`` casting operator,
+or with the return value of ``$object->__debugInfo()`` if the magic method exists.
+Then, the return value of one Caster is given as argument to the next Caster in the chain.
+
+When casting with the ``(array)`` operator, PHP prefixes protected properties with a ``\0*\0``
+and private ones with the class owning the property: e.g. ``\0Foobar\0`` prefixes all private properties
+of objects of type Foobar. Casters follow this convention and add two more prefixes: ``\0~\0`` is used for
+virtual properties and ``\0+\0`` for dynamic ones (runtime added properties not in the class declaration).
+
+.. note::
+
+    Although you can, it is best advised not to alter the state of an object while casting it in a Caster.
