-## [bpmn-js](https://github.com/bpmn-io/bpmn-js) Extension
+# Behaviors
 
-We include an extension that makes [bpmn-js](https://github.com/bpmn-io/bpmn-js) copy and replace mechanisms aware of Zeebe properties.
-
-```js
-var BpmnJS = require('bpmn-js/lib/Modeler'),
-    zeebeExtensionModule = require('zeebe-bpmn-moddle/lib'),
-    zeebeModdle = require('zeebe-bpmn-moddle/resources/zeebe');
-
-var modeler = new BpmnJS({
-    additionalModules: [
-      zeebeExtensionModule
-    ],
-    moddleExtensions: {
-      zeebe: zeebeModdle
-    }
-  });
-```
-
-This extension hooks into the copy mechanism provided by the BPMN editor and ensures Zeebe properties are kept and or dropped on copy and element replace.
+This extension should be used with [camunda-bpmn-js-behaviors](https://github.com/camunda/camunda-bpmn-js-behaviors#camunda-platform-8) to ensure Camunda properties are created, updated and deleted as expected.
