+
+        The basic new concept introduced is a <em>path</em>:<br/>
+        A <em>path</em> is a sequence of states, which are to be executed in a linear order.
+        Elements in the path can be skipped, depending on choices the user makes.
+
+        In the most simple wizards, you will have only one path consisting of <code>n</code> elements,
+        which are to be visited successively.
+
+        In a slightly more complex wizard, you will have one linear path, were certain
+        steps might be skipped due to user input. For instance, the user may decide to not specify
+        certain aspects of the to-be-created object (e.g. by unchecking a check box),
+        and the wizard then will simply disable the step which corresponds to this step.
+
+        In a yet more advanced wizards, you will have several paths of length <code>n1</code> and
+        <code>n2</code>, which share at least the first <code>k</code> states (where <code>k</code>
+        is at least 1), and an arbitrary number of other states.
