 =head1 SYNOPSIS
 
-    setting session => 'PSGI'
+A basic psgi application
+
+    use strict; use warnings;
+    use Plack::Builder;
+
+    my $app = sub {
+        my $session = (shift)->{'psgix.session'};
+        return [
+            200,
+            [ 'Content-Type' => 'text/plain' ],
+            [ "Hello, you've been here for ", $session->{counter}++, "th time!" ],
+        ];
+    };
+
+    builder { enable 'Session', store => 'File'; $app; };
+
+In your app.psgi:
+
+    builder {
+        enable "Session", store => "File";
+        sub { my $env = shift; my $request = Dancer::Request->new($env); Dancer->dance($request);};
+    };
+
+And a simple Dancer application:
+
+   package session;
+   use Dancer ':syntax';
+
+    get '/' => sub {
+        my $count = session("counter");
+        session "counter" => ++$count;
+        template 'index', {count => $count};
+    };
+
+Now, your two applications can share the same session informations.
