+Only jump into this section if you are familiar with iterators, circulators,
+the notion of `Edge`, locate type and locate index explained in the previous section.
+
 In case the input is not just points but also segments in the plane, a constrained
 triangulation has edges that do not cross constraints. A constraint may be a
 single edge or split into several edges in case constraints intersect or in case
 an input pout lies on a constraint.
 
+In this section we first explain the API of the class template `Constrained_Delaunay_triangulation_2`,
+and then `Constrained_triangulation_plus_2`, admittedly a strange name.
