+Writing to Array Properties
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The ``PropertyAccessor`` class allows to update the content of arrays stored in
+properties through *adder* and *remover* methods.

+    {
+        /**
+         * @var string[]

+
+The PropertyAccess component checks for methods called ``add<SingularOfThePropertyName>()``
+and ``remove<SingularOfThePropertyName>()``. Both methods must be defined.
+For instance, in the previous example, the component looks for ``addChild()`` and
+``removeChild()`` methods to access to the ``children`` property.
+`The Inflector component`_ is used to find the singular of a property name.
+
+If available, *adder* and *remover* methods have priority over a *setter* method.
