-## Overview
+# Overview
 [Milvus](https://milvus.io) is a cloud-native, open-source vector database built to manage embedding vectors generated by machine learning models and neural networks. It extends the capabilities of best-in-class approximate nearest neighbor (ANN) search libraries (e.g. Faiss, NMSLIB, Annoy) and features on-demand scalability, and high availability.
 
 The Milvus Operator provides an easy and solid solution to deploy and manage a full Milvus service stack including both the milvus components and its relevant dependencies such as etcd, pulsar and minio to the target [Kubernetes](https://kubernetes.io/) clusters in a scalable and high-available way. The Milvus Operator defines a `Milvus` custom resources on top of Kubernetes [Custom Resources](https://kubernetes.io/docs/concepts/extend-kubernetes/api-extension/custom-resources/). The Kubernetes API can then be used in a declarative way to manage Milvus deployment stack and ensure its scalability and high-availability operation.

+## Dynamic configuration update
+
+Since Milvus Operator v1.0.0 you can dynamically update the configuration of Milvus(of v2.4.5+) components without restarting it. First you need to set `spec.components.updateConfigMapOnly` to `true` to avoid restarting components when update config. Then You can change the configuration of a running Milvus cluster by updating the `spec.config` field in the Milvus CRD. for example, update `dataCoord.segment.diskSegmentMaxSize` to `4096MB` from initial `2048MB`:
+```yaml
+apiVersion: milvus.io/v1beta1
+kind: Milvus
+metadata:
+  name: my-release
+  labels:
+    app: milvus
+spec:
+  config: 
+    dataCoord:
+      segment:
+        diskSegmentMaxSize: 4096
+  components:
+    updateConfigMapOnly: true
+```
+
+> Note: not all fields in the `milvus.yaml` can be dynamically updated. You can refer to the [Applicable configuration items](https://milvus.io/docs/dynamic_config.md#Applicable-configuration-items) for more details.
+
 ## Configuration for Milvus dependencies
 
 There're also configuration sections about milvus's dependencies in the `milvus.yaml` (like `minio`, `etcd`, `pulsar`...). Usually you don't need to change these configurations, because the Milvus Operator will set them automatically according to your specifications in `spec.dependencies.<dependency name>` field.
