 ## About Backbone.EventBinder
 
@@ -14,6 +14,16 @@ Backbone.EventBinder provides a simple mechanism for cleaning up your
 event bindings, including the ability to clean up anonymous callback
 functions!
 
+## Obsolete With Backbone v0.9.9+
+
+Backbone v0.9.9 introduced two new methods to the Backbone.Events
+object: `listenTo` and `stopListening`. These methods are direct
+replacements for Backbone.EventBinder.
+
+If you are using Backbone v0.9.9 or higher, you do not need this
+plugin. This repository will stick around for those using Backbone
+v0.9.2, though.
