+Deploying with LWS
+============================
+
+LeaderWorkerSet (LWS) is a Kubernetes API that aims to address common deployment patterns of AI/ML inference workloads.
+A major use case is for multi-host/multi-node distributed inference.
+
+vLLM can be deployed with `LWS <https://github.com/kubernetes-sigs/lws>`_ on Kubernetes for distributed model serving.
+
+Please see `this guide <https://github.com/kubernetes-sigs/lws/tree/main/docs/examples/vllm>`_ for more details on
+deploying vLLM on Kubernetes using LWS.
