+Group Sequence
+--------------
+
+In some cases, you want to validate your groups by steps. To do this, you can
+use the ``GroupSequence`` feature. In the case, an object defines a group sequence,
+and then the groups in the group sequence are validated in order.
+
+.. tip::
+
+    Group sequences cannot contain the group ``Default``, as this would create
+    a loop. Instead, use the group ``{ClassName}`` (e.g. ``User``) instead.
+
+For example, suppose you have a ``User`` class and want to validate that the
+username and the password are different only if all other validation passes
+(in order to avoid multiple error messages).
