 =head1 DESCRIPTION
 
-=head1 ROLES
+Moose::Autobox provides an implementation of SCALAR, ARRAY, HASH
+& CODE for use with L<autobox>. It does this using a hierarchy of 
+roles in a manner similar to what Perl 6 I<might> do. This module, 
+like L<Class::MOP> and L<Moose>, was inspired by my work on the 
+Perl 6 Object Space, and the 'core types' implemented there.

+=head2 A quick word about autobox
 
-  * indicates actual autoboxed types
+The L<autobox> module provides the ability for calling 'methods' 
+on normal Perl values like Scalars, Arrays, Hashes and Code 
+references. This gives the illusion that Perl's types are first-class 
+objects. However, this is only an illusion, albeit a very nice one.
+I created this module because L<autobox> itself does not actually 
+provide an implementation for the Perl types but instead only provides 
+the 'hooks' for others to add implementation too.
 
+=head2 Is this for real? or just play?
+
+Several people are using this module in serious applications and 
+it seems to be quite stable. The underlying technologies of L<autobox>
+and L<Moose::Role> are also considered stable. There is some performance
+hit, but as I am fond of saying, nothing in life is free. If you have 
+any questions regarding this module, either email me, or stop by #moose
+on irc.perl.org and ask around.
+
+=head2 Adding additional methods
+
+B<Moose::Autobox> asks L<autobox> to use the B<Moose::Autobox::*> namespace 
+prefix so as to avoid stepping on the toes of other L<autobox> modules. This 
+means that if you want to add methods to a particular perl type 
+(i.e. - monkeypatch), then you must do this:
+
+  sub Moose::Autobox::SCALAR::bar { 42 }
+
+instead of this:
+
+  sub SCALAR::bar { 42 
+
+as you would with vanilla autobox.
+
+=head1 METHODS
+
+=over 4
+
+=item B<mixin_additional_role ($type, $role)>
+
+This will mixin an additonal C<$role> into a certain C<$type>. The 
+types can be SCALAR, ARRAY, HASH or CODE.
+
+This can be used to add additional methods to the types, see the 
+F<examples/units/> directory for some examples.
