+=head1 DESCRIPTION
 
-=item B<constraint_generator>
+This class represents a parameterizable type constraint. This is a
+type constraint like C<ArrayRef> or C<HashRef>, that can be
+parameterized and made more specific by specifying a contained
+type. For example, instead of just an C<ArrayRef> of anything, you can
+specify that is an C<ArrayRef[Int]>.
 
-=item B<has_constraint_generator>
+A parameterizable constraint should not be used as an attribute type
+constraint. Instead, when parameterized it creates a
+L<Moose::Meta::TypeConstraint::Parameterized> which should be used.
 
-=item B<generate_constraint_for>
+=head1 INHERITANCE
 
-=item B<parameterize>
+C<Moose::Meta::TypeConstraint::Parameterizable> is a subclass of
+L<Moose::Meta::TypeConstraint>.
 
-Given a single type constraint string, this method parses the string
-and parameterizes the type based on the parsed string.

+=head1 METHODS
 
-=back
+This class is intentionally not documented because the API is
+confusing and needs some work.
