-### registerOrUpdateElement(elementName, prototype)
+### registerOrUpdateElement(elementName, options)
 
 Registers or updates a custom element whose name is `elementName`.
 
 ```coffee
 {registerOrUpdateElement} = require 'atom-utils'
 
 class MyElement
+  @staticMethod: ->
+    console.log 'in static method'
+
   createdCallback: ->
     console.log 'element created'
 
-registerOrUpdateElement('my-element', MyElement.prototype)
+MyElement = registerOrUpdateElement('my-element', class: MyElement)
 ```
 
-The update is performed by copying the properties from the passed-in prototype in the registered element prototype. As a node's callback methods can't be overriden once the element have been registered, a generic version is created that will invoke the concrete callback when called, that way even the node's callback methods can be updated.

+Only the class' prototype can be passed using the `prototype` option instead of `class`.
