+=head1 NAME
+
+MooseX::Daemonize::WithPidFile - A Role with the core daemonization and pidfile management
+
+=head1 SYNOPSIS
+
+  package My::Daemon;
+  use Moose;
+
+  with 'MooseX::Daemonize::WithPidFile';
+
+  sub start {
+      my $self = shift;
+      # daemonize me ...
+      $self->daemonize; # << this will write the pidfile for you
+      # return from the parent,...
+      return unless $self->is_daemon;
+      # but continue on in the child (daemon)
+  }
+
+=head1 DESCRIPTION
+
+This is a slightly extended basic daemonization Role, it provides 
+Pidfile management along with the core daemonization features 
+found in L<MooseX::Daemonize::Core>.
+
+=head1 ATTRIBUTES
+
+=over
+
+=item I<pidfile (is => rw, isa => MooseX::Daemonize::Pid::File)>
+
+This attribute holds the L<MooseX::Daemonize::Pid::File> object used
+to manage the Pidfile. It will initialize the object using the 
+C<init_pidfile> method (which is required by this role).
+
+=back
+
+=head1 REQUIRED METHODS
+
+=over 4
+
+=item I<init_pidfile>
+
+This method is used to build the I<pidfile> attribute's object. It should
+return a L<MooseX::Daemonize::Pid::File> object.
+
+=item B<has_pidfile>
+
+This is a predicate method to tell you if your I<pidfile> attribute has 
+been initialized yet.
+
+=back
+
+=head1 METHODS
+
+=over 4
+
+=item B<daemonize>
+
+This adds an C<after> method modifier to the C<daemonize> method (from 
+L<MooseX::Daemonize::Core>) and handles writing your Pidfile for you.
+
+=item B<meta>
+
+The C<meta()> method from L<Class::MOP::Class>
+
