+**Hephy Workflow** is the open source fork of Deis Workflow PaaS. Some of the old documentation and README are still preserved so they may reference "Deis Workflow". Hephy Workflow is the community continuation of the Deis Workflow project after it was end-of-lifed by the Deis team which moved on to do bigger projects at Microsoft Azure.
+
 **Deis Workflow** is an open source Platform as a Service (PaaS) that adds a developer-friendly layer to any [Kubernetes][k8s-home] cluster, making it easy to deploy and manage applications.
 
 Deis Workflow is the second major release (v2) of the Deis PaaS. If you are looking for the CoreOS-based PaaS visit [https://github.com/deis/deis](https://github.com/deis/deis).
