+Attachments uploaded to Azure Storage instead of directly to Common Data Service can be managed by using notes in Common Data Service.
 
 To enable attachments from a particular form to be uploaded into Azure Storage, you must add a web resource to that form and you must [configure Azure Storage for your organization](enable-azure-storage.md).
 
 > [!NOTE]
-In this example, the form is added to the Lead form for the Lead entity. We recommend using caution when editing existing forms.
