 In `Notifications.h` you will use a preprocessor statement to declare your notifications. Declare one per line. For example:
 
-    PubSub(nameChanged, NSString)
-    
+    PubSub(somethingHappened) // zero arguments
+
+    PubSub(nameChanged, NSString*) // one arguments
+
+    /*
+    NOT supported yet (but would be cool)
+    PubSub(multipleArgsCommand, NSString*, BOOL, NSString*) // multiple arguments...
+    */
+
 This generates two strongly typed methods that look kinda like this:
 
     @interface Pub
+    + (void) somethingHappened;
     + (void) nameChanged:(NSString*)arg;
     @end
     @interface Sub
+    + (void) while:(id)obj somethingHappened:(void(^)(void))callback;
     + (void) while:(id)obj nameChanged:(void(^)(NSString*))callback;
     @end

+You can't use value types such as `int`, `BOOL`, etc in the PubSub macro... _If someone could help me figure out a way to acomplish this (possibly through some macro tricks) I'd love the feedback!_

 ## PubSub-iOS
 
 PubSub-iOS is a very simple, block based wrapper around `NSNotificationCenter`.

+# WARNING:
+I love the concept of this project and the simplicity of declaring, consuming and publishing of notifications it provides. However, I've recently pulled it out of a project I was using due to a number of random crashes - if anyone more Objective-C versed than I could have a look I'd love some feedback. But for now - BEWARE :P
