+## Avoid a Workflow instance to fail
+
+Any uncaught exceptions that propagate to the top level, or any steps that reach their retry limit, will cause the Workflow to end execution in an Errored state. However, this may not be intended, as for example, a cleanup of previous step executions may be required.
+
+To allow the Workflow to continue its execution, surround the intended steps that are allowed to fail with a try/catch.
+
+Simple example of a Worflow with a cleanup step:
 
 ```ts
 ...
+await step.do('task', async () => {

 try {
-    await step.do('task', async () => {

 		// work not to be retried
         throw new NonRetryableError('oh no');
