 added support for `actor.system.subscribe` to subscribe to registration and unregistration events within an actor's system.
+`actor.system.subscribe` returns a `Subscription` object you can `.unsubscribe` to at any time.
 
-you can use `actor.system.subscribe` in two ways:
+ex:
 
-- `actor.system.subscribe(event => ...)` subscribes to all registration/unregistration events occurring within the system
-- `actor.system.subscribe(systemId, event => ...)` subscribes to the registration/unregistration events of that given systemId.
+```js
+// observer object
+const subscription = actor.system.subscribe({
+  next: (event) => console.log(event),
+  error: (err) => console.error(err),
+  complete: () => console.log('done')
+});
 
-`actor.system.subscribe` returns a `Subscription` object you can `.unsubscribe` to at any time.
+// observer parameters
+const subscription = actor.system.subscribe(
+  (event) => console.log(event),
+  (err) => console.error(err),
+  () => console.log('done')
+);
+
+// callback function
+const subscription = actor.system.subscribe((event) => console.log(event));
+
+// unsubscribe
