+This is the core session object, you probably want to look

-=item B<new ( %params )>

-The constructor expects keys in C<%params> for I<state>,
-I<store> and I<request>. The I<request> param is expected to be
-a L<Plack::Request> instance or an object with an equivalent
-interface.
+The constructor takes a PSGI request env hash reference.
 
 =item B<id>
 
 This is the accessor for the session id.
 
-=item B<state>
-
-This is expected to be a L<Plack::Session::State> instance or
-an object with an equivalent interface.

-=item B<store>
-
-This is expected to be a L<Plack::Session::Store> instance or
-an object with an equivalent interface.

-These methods delegate to appropriate methods on the C<store>.
+These methods allows you to read and write the session data like
