+## Adding out-of-hours workflow
 
+When we create an auto attendant we don't need to specify an out-of-hours workflow. If we hit **Submit** in the **Call flow** window (as in the image below), it won't be created:
 
+![](../../img/20220204-134305-axntyw9ix9.png "Call flow window in auto attendant creator")
 
-## Changing out of hours greeting
+We can check if that's the case by inspecting the value of the *Call flows* property in the `$aa` variable. If it's empty, as in the image below, the out-of-hours workflow is not defined:
+
+ 
+
+![](../../img/20220204-134647-r5p68s9p2h.png "Inspecting Call Flows value via PowerShell")
+
+If there's no out-of-hours workflow, we won't be able to modify it. Modifying is described in the later stages. Let's now take care of the workflow.
+
+To create a workflow, we'll use [`New-CsAutoAttendantCallFlow` cmdlet](https://docs.microsoft.com/en-us/powershell/module/skype/new-csautoattendantcallflow?view=skype-ps). 
+
+<Warning>
 
+The script below assumes there's no holiday workflow. If there's one defined, it'll be overwritten!
