-Stable vLLM Docker images are being pre-built for Arm from version 0.12.0. Available image tags are here: [https://gallery.ecr.aws/q9t5s3a7/vllm-arm64-cpu-release-repo](https://gallery.ecr.aws/q9t5s3a7/vllm-arm64-cpu-release-repo).
+```bash
+docker pull public.ecr.aws/q9t5s3a7/vllm-arm64-cpu-release-repo:latest

+
+To pull an image with a specific vLLM version:
 
 ```bash
 export VLLM_VERSION=$(curl -s https://api.github.com/repos/vllm-project/vllm/releases/latest | jq -r .tag_name | sed 's/^v//')
 docker pull public.ecr.aws/q9t5s3a7/vllm-arm64-cpu-release-repo:v${VLLM_VERSION}
 ```
 
+All available image tags are here: [https://gallery.ecr.aws/q9t5s3a7/vllm-arm64-cpu-release-repo](https://gallery.ecr.aws/q9t5s3a7/vllm-arm64-cpu-release-repo).
+
+You can run these images via:
+
+```bash
+docker run \
+    -v ~/.cache/huggingface:/root/.cache/huggingface \
+    -p 8000:8000 \
+    --env "HF_TOKEN=<secret>" \
+    public.ecr.aws/q9t5s3a7/vllm-arm64-cpu-release-repo:<tag> <args...>
+```
+
 You can also access the latest code with Docker images. These are not intended for production use and are meant for CI and testing only. They will expire after several days.
 
 The latest code can contain bugs and may not be stable. Please use it with caution.

 !!! warning
     If deploying the pre-built images on machines without `avx512f`, `avx512_bf16`, or `avx512_vnni` support, an `Illegal instruction` error may be raised. See the build-image-from-source section below for build arguments to match your target CPU capabilities.
