    // Set up the directory we are syncing.
    self.myFolderURL = [NSURL fileURLWithPath:@"/Users/hmaass/Downloads"];
    [FIFinderSyncController defaultController].directoryURLs = [NSSet setWithObject:self.myFolderURL];

    // Set up images for our badge identifiers. For demonstration purposes, this uses off-the-shelf images.
    [[FIFinderSyncController defaultController] setBadgeImage:[NSImage imageNamed: NSImageNameColorPanel] label:@"Status One" forBadgeIdentifier:@"One"];
    [[FIFinderSyncController defaultController] setBadgeImage:[NSImage imageNamed: NSImageNameCaution] label:@"Status Two" …
