+
+This chart deploys the standalone HAMi Ascend device plugin manifests:
+
+- RuntimeClass
+- ConfigMaps
+- RBAC and ServiceAccount
+- Device plugin DaemonSet
+
+## Install
+
+Label Ascend nodes before installing:
+
+```bash
+kubectl label node <ascend-node> ascend=on --overwrite
+```
+
+Install the chart:
+
+```bash
+helm install ascend-device-plugin ./charts/ascend-device-plugin \
+  --namespace kube-system
+```
+
+If the HAMi chart already manages the Ascend device plugin DaemonSet, related ConfigMaps, RBAC, or RuntimeClass, do not deploy this standalone chart at the same time.
+
+## Existing Device Configuration
+
+If another chart, such as the HAMi chart, already owns the shared `hami-scheduler-device` ConfigMap, reuse it instead of creating another one:
+
+```bash
+helm install ascend-device-plugin ./charts/ascend-device-plugin \
+  --namespace kube-system \
+  --set config.create=false \
+  --set config.existingDeviceConfigMapName=hami-scheduler-device
+```
+
+With this mode, the chart mounts the existing device config and still manages `hami-device-node-config` by default.
+
+## hami-vnpu-core
+
+Enable the global `vnpus.hamiVnpuCore` switch in the generated device config:
+
+```bash
+helm install ascend-device-plugin ./charts/ascend-device-plugin \
+  --namespace kube-system \
+  --set hamiVnpuCore.enabled=true
+```
+
+## Node Configuration
+
+Override `nodeConfig` to enable or customize `hami-vnpu-core` per node:
+
+```yaml
+nodeConfig: |-
+  nodes:
+    - name: "ascend-node-1"
+      hami-vnpu-core: true
+      vDeviceCount: 8
+```
