+==========================
+
+Each configured validation consist of an array with validation settings.
+Each entry needs at least the following options:
+
+``validator``
+   The Validator to use, the same way you would use in usual way.
+   E.g. use short names for Framework validators like ``StringLength`` or full path for custom
+   validators like ``DigiComp.SettingValidator:Settings``.
+``options``
+   An array of options to provide for the validator.
+   The same as you would have done through the usual way.
+   If the validator doesn't take arguments, provide an empty array.
+
+Also there are some optional options:
+
+``property``
+   Optional, used to configure validation for a property of the object the validation is applied to.
