-=head1 SYNOPSIS
+Moose::Object - The base object for Moose
 
 =head1 DESCRIPTION
 
+This serves as the base object for all Moose classes. Every 
+effort will be made to ensure that all classes which C<use Moose> 
+will inherit from this class. It provides a default constructor 
+and destructor, which run all the BUILD and DEMOLISH methods in 
+the class tree.
+
+You don't actually I<need> to inherit from this in order to 
+use Moose though. It is just here to make life easier.
+
 =head1 METHODS
 
 =over 4
 
 =item B<meta>
 
+This will return the metaclass associated with the given class.
+
 =item B<new>
 
+This will create a new instance and call C<BUILDALL>.
+
 =item B<BUILDALL>
 
+This will call every C<BUILD> method in the inheritance hierarchy, 
+and pass it a hash-ref of the the C<%params> passed to C<new>.
+
 =item B<DEMOLISHALL>
 
+This will call every C<DEMOLISH> method in the inheritance hierarchy.
+
+=item B<does ($role_name)>
+
+This will check if the invocant's class C<does> a given C<$role_name>. 
+This is similar to C<isa> for object, but it checks the roles instead.
+
+=item B<dump ($maxdepth)>
+
+Cmon, how many times have you written the following code while debugging:
+
+ use Data::Dumper; 
+ warn Dumper $obj;
+
+It can get seriously annoying, so why not just use this.
