 From a technical view, vllm-ascend support would be possible if the torch-npu is supported. Otherwise, we have to implement it by using custom ops. We are also welcome to join us to improve together.
+
+### 2. How to get our docker containers?
+
+You can get our containers at `Quay.io`, e.g., [<u>vllm-ascend</u>](https://quay.io/repository/ascend/vllm-ascend?tab=tags) and [<u>cann</u>](https://quay.io/repository/ascend/cann?tab=tags).
+
+If you are in China, you can use `daocloud` to accelerate your downloading:
+
+1) Open `daemon.json`:
+
+```bash
+vi /etc/docker/daemon.json
+```
+
+2) Add `https://docker.m.daocloud.io` to `registry-mirrors`:
+
+```json
+{
+  "registry-mirrors": [
+        "https://docker.m.daocloud.io"
+    ]
+}
+```
+
+3) Restart your docker service:
+
+```bash
+sudo systemctl daemon-reload
+sudo systemctl restart docker
+```
+
+After configuration, you can download our container from `m.daocloud.io/quay.io/ascend/vllm-ascend:v0.7.3rc2`.
+
