+This SDK provides a method for popping up a Facebook dialog. The currently supported dialogs are the login and permissions dialogs used in the authorization flow, and a dialog for publishing posts to a user's feed.
 
 To invoke a dialog:
 
-        NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys: apiKey, @"api_key", nil];
-        [facebook dialog:@"stream.publish" andParams:params andDelegate:self];
+        [facebook dialog:@"feed" andDelegate:self];
 
 This allows you to provide basic Facebook functionality in your application with a singe line of code -- no need to build native dialogs, make API calls, or handle responses. For further examples, refer to the included sample application.
