+vLLM is also available via [Llama Stack](https://github.com/meta-llama/llama-stack) .
+
+To install Llama Stack, run
+
+```console
+pip install llama-stack -q
+```
+
+## Inference using OpenAI Compatible API
+
+Then start Llama Stack server pointing to your vLLM server with the following configuration:
+
+```yaml
+inference:
+  - provider_id: vllm0
+    provider_type: remote::vllm
+    config:
+      url: http://127.0.0.1:8000
+```
+
+Please refer to [this guide](https://llama-stack.readthedocs.io/en/latest/distributions/self_hosted_distro/remote-vllm.html) for more details on this remote vLLM provider.
+
+## Inference via Embedded vLLM
+
+An [inline vLLM provider](https://github.com/meta-llama/llama-stack/tree/main/llama_stack/providers/inline/inference/vllm)
+is also available. This is a sample of configuration using that method:
+
