-To deploy mission-critical logic apps that are always available and responsive, even during updates or maintenance, you can enable zero downtime deployment by creating and using deployment slots. Zero downtime means that when you deploy new versions of your app, end users shouldn't experience disruption or downtime. Deployment slots are isolated nonproduction environments that host different versions of your app and provide the following benefits:

+Deployment slots provide the following benefits:
 
+- Swap a deployment slot with your production slot without interruption. That way, you can update your logic app and workflows without affecting availability or performance.
+- Validate any changes in a deployment slot before you apply those changes to the production slot.
 - Roll back to a previous version, if anything goes wrong with your deployment.
-
 - Reduce the risk of negative performance when you must exceed the [recommended number of workflows per logic app](create-single-tenant-workflows-azure-portal.md#best-practices-and-recommendations).
 
-With deployment slots, you can achieve continuous delivery and improve your applications' quality and reliability. For more information about deployment slots in Azure and because Standard logic app workflows are based on Azure Functions extensibility, see [Azure Functions deployment slots](../azure-functions/functions-deployment-slots.md).

 ### Known issues and limitations
 
 - Nonproduction slots are created in read-only mode.
-
 - The nonproduction slots dispatcher is turned off, which means that workflows can only run when they're in the production slot.
-
 - Traffic distribution is disabled for deployment slots in Standard logic apps.

 - Deployment slots for Standard logic apps don't support the following scenarios:
