+Azure Fleet repo contains the code that the [Azure Kubernetes Fleet Manager](https://learn.microsoft.com/en-us/azure/kubernetes-fleet/) service uses to provide multi-cluster workload scheduling and management capabilities. 
 
-KubeFleet is a sandbox project of the [Cloud Native Computing Foundation](https://cncf.io/) (CNCF) that works on any Kubernetes cluster.
-We are working towards the vision where we will eventually be able to treat each Kubernetes cluster as a [cattle](https://cloudscaling.com/blog/cloud-computing/the-history-of-pets-vs-cattle/).
+It follows the CNCF sandbox project [KubeFleet](https://github.com/kubefleet-dev/) and most of the development is done in the [KubeFleet](https://github.com/kubefleet-dev/).
 
+## Get Involved 
+For any questions, please see the [KubeFleet discussion board](https://github.com/kubefleet-dev/kubefleet/discussions).
