 <h2 align="center">How to write custom steps</h2>
 
 If you're not familiar with CUE, please checkout the [CUE documentation](https://kubevela.io/docs/platform-engineers/cue/basic) first.
 
 You can customize your steps with CUE and some [built-in operations](https://kubevela.io/docs/platform-engineers/workflow/cue-actions). Please checkout the [tutorial](https://kubevela.io/docs/platform-engineers/workflow/workflow) for more details.
 
+> Note that you cannot use the [application operations](https://kubevela.io/docs/next/platform-engineers/workflow/cue-actions#application-operations) since there're no application data like components/traits/policy in the WorkflowRun.
