How pass data in seque ios5 storyboard uitableview to detail view

I'm creating an app in ios5 using storyboards. I have a tableviewcontroller embedded in a navigation controller and when you click on the cells in the tableviewcontroller some detail about that cell topic should be passed to a detail view. I use a plist to populate the tableview and the detail view. I've done this fine without using storyboard but want to learn how to use storyboard. I have seque going to my detail view from the tableviewcontroller.

My code for the seque is:

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([segue.identifier isEqualToString:@"DetailViewControllerSeque"])
    {   DetailViewController *detailViewController = [segue destinationViewController];  
        NSString *path = [[NSBundle mainBundle] bundlePath];
        NSString *finalPath = [path stringByAppendingPathComponent:@"questList.plist"];
        NSArray *tempArray = [finalPath valueForKey:@"description"];
        NSString *descriptionString = [tempArray valueForKey:@"description"];
        detailViewController.detailDescriptionText.text = descriptionString;    
    }
}

Thanks for any help.
