 Plack::Session::State - Basic parameter-based session state
 
+=head1 SYNOPSIS
+
+  use Plack::Builder;
+  use Plack::Middleware::Session;
+  use Plack::Session::State;
+
+  my $app = sub {
+      return [ 200, [ 'Content-Type' => 'text/plain' ], [ 'Hello Foo' ] ];
+  };
+
+  builder {
+      enable 'Session',
+          state => Plack::Session::State->new;
+      $app;
+  };
+
 =head1 DESCRIPTION
 
+This will maintain session state by passing the session through
+the request params. It does not do this automatically though,
+you are responsible for passing the session param.
+
+This should be considered the state "base" class (although
+subclassing is not a requirement) and defines the spec for
+all B<Plack::Session::State::*> modules. You will only
+need to override a couple methods if you do subclass. See
+L<Plack::Session::State::Cookie> for an example of this.
