 ### Sidecars
 
-If additional containers are needed in the same pod as milvus (such as additional metrics or logging exporters), they can be defined using the `sidecars` parameter inside each of the subsections: `client`, `worker`. If these sidecars export extra ports, extra port definitions can be added using the `service.extraPorts` parameter. [Learn more about configuring and using sidecar containers](https://docs.bitnami.com/kubernetes/infrastructure/deepspeed/configuration/configure-sidecar-init-containers/).
+If additional containers are needed in the same pod as Milvus (such as additional metrics or logging exporters), they can be defined using the `sidecars` parameter.
+
+```yaml
+sidecars:
+- name: your-image-name
+  image: your-image
+  imagePullPolicy: Always
+  ports:
+  - name: portname
+    containerPort: 1234
+```
+
+If these sidecars export extra ports, extra port definitions can be added using the `service.extraPorts` parameter (where available), as shown in the example below:
+
+```yaml
+service:
+  extraPorts:
+  - name: extraPort
+    port: 11311
+    targetPort: 11311
+```
+
+> NOTE: This Helm chart already includes sidecar containers for the Prometheus exporters (where applicable). These can be activated by adding the `--enable-metrics=true` parameter at deployment time. The `sidecars` parameter should therefore only be used for any extra sidecar containers.
+
+If additional init containers are needed in the same pod, they can be defined using the `initContainers` parameter. Here is an example:
+
+```yaml
+initContainers:
+  - name: your-image-name
+    image: your-image
+    imagePullPolicy: Always
+    ports:
+      - name: portname
+        containerPort: 1234
