+
+#### Get the correct docker environment
+
+The v0.11.0 releases is on Oct 3, 2025, so we will pull a AMD nightly docker image close to the release period. `rocm/vllm-dev:nightly_main_20251005` is picked as it has a correct `transformers` version that supports qwen3_omni.
+
+`docker pull rocm/vllm-dev:nightly_main_20251005`
+
+#### Launch the docker environment
+
+In this docker environment, we have all the dependencies for vLLM installed, like `flash-attn` and `aiter`
+
+```bash
+#!/bin/bash
+docker run -it \
+   --privileged \
+   --network=host \
+   --group-add=video \
+   --ipc=host \
+   --cap-add=SYS_PTRACE \
+   --security-opt seccomp=unconfined \
+   --device /dev/kfd \
+   --device /dev/dri \
+   --name vllmomni \
+   rocm/vllm-dev:nightly_main_20251005 \
+   bash
+```
+
+#### Update docker dependencies
+
+```bash
+sudo apt update
+sudo apt install ffmpeg -y
+```
+
+#### Installation of vLLM
+Install the v0.11.0 release of vLLM as vLLM-Omni is currently depend on v0.11.0.
+
+```bash
+# uninstall existing vllm which is based on the main branch, not on the releases branch
+python3 -m pip uninstall -y vllm
+git clone https://github.com/vllm-project/vllm.git vllm0110
+cd vllm0110/
+
+# checkout the version tag v0.11.0
+git checkout -b v0.11.0 v0.11.0
+
+# you should see 0.11.0
+python -c "import setuptools_scm; print(setuptools_scm.get_version())"
+
+# PYTORCH_ROCM_ARCH=<your-gpu-arch> python3 setup.py develop
+PYTORCH_ROCM_ARCH=gfx942 python3 setup.py develop
+```
+
+!!! note
+    vLLM release wheels based on the branch with prefix `releases/`, not from the tag as vLLM may cherry pick bugfixes after cutting a branch.
+
+
+#### Installation of vLLM-Omni
+
+There are two approaches to installing `vllm-omni`
+
+
+1. Install from PyPI
+
+```bash
+pip install vllm-omni
+
+# you might want to also download the source code of the same version to run the examples
+```
+
+2. Install from source
+
+```bash
+# clone and checkout to the release version.
+git clone https://github.com/vllm-project/vllm-omni.git
+cd vllm-omni
+git checkout v0.11.0rc1
+pip install -e .
+```
+
+#### Setup Environment Variables
+
+After installing `vllm` and `vllm-omni` please setup the environment variable as well before running any of the examples and command.
+
+```bash
+export MIOPEN_FIND_MODE=FAST
+export VLLM_ROCM_USE_AITER=1
+export VLLM_ROCM_USE_AITER_MHA=1
+export VLLM_ROCM_USE_AITER_LINEAR=0
+export VLLM_ROCM_USE_AITER_RMSNORM=0
+```
