Moose::Meta::TypeConstraint::Enum - Type constraint for enumerated values.
+=head1 DESCRIPTION
+
+This class represents type constraints based on an enumerated list of
+acceptable values.
+
+=head1 INHERITANCE
+
+C<Moose::Meta::TypeConstraint::Enum> is a subclass of
+L<Moose::Meta::TypeConstraint>.
+
=head1 METHODS
=over 4
-=item B<new>
+=item B<< Moose::Meta::TypeConstraint::Enum->new(%options) >>
+
+This creates a new class type constraint based on the given
+C<%options>.
+
+It takes the same options as its parent, with several
+exceptions. First, it requires an additional option, C<values>. This
+should be an array reference containing a list of valid string
+values. Second, it automatically sets the parent to the C<Str> type.
+
+Finally, it ignores any provided C<constraint> option. The constraint
+is generated automatically based on the provided C<values>
+
+=item B<< $constraint->values >>
-=item B<equals>
+Returns the array reference of acceptable values provided to the
+constructor.
-=item B<constraint>
+=item B<< $constraint->create_child_type >>
-=item B<values>
+This returns a new L<Moose::Meta::TypeConstraint> object with the type
+as its parent.
-=item B<meta>
+Note that it does I<not> return a C<Moose::Meta::TypeConstraint::Enum>
+object!
