+# Install NebulaGraph Operator
+
+You can deploy NebulaGraph Operator with [Helm](https://helm.sh/).
+
+## Background
+
+[NebulaGraph Operator](../1.introduction-to-nebula-operator.md) automates the management of NebulaGraph clusters, and eliminates the need for you to install, scale, upgrade, and uninstall NebulaGraph clusters, which lightens the burden on managing different application versions.
+
+## Prerequisites
+
+Before installing NebulaGraph Operator, you need to install the following software and ensure the correct version of the software :
+
+| Software                                                         | Requirement  |
+| ------------------------------------------------------------ | --------- |
+| [Kubernetes](https://kubernetes.io)                          | \>= 1.18  |
+| [Helm](https://helm.sh)                                      | \>= 3.2.0 |
+| [CoreDNS](https://github.com/coredns/coredns)                | \>= 1.6.0 |
+
+!!! note
+
+    - If using a role-based access control policy, you need to enable [RBAC](https://kubernetes.io/docs/admin/authorization/rbac) (optional).
+
+    - [CoreDNS](https://coredns.io/) is a flexible and scalable DNS server that is [installed](https://github.com/coredns/helm) for Pods in NebulaGraph clusters.
+
+## Steps
+
+1. Add the NebulaGraph Operator Helm repository.
+
+  ```bash
+  helm repo add nebula-operator https://vesoft-inc.github.io/nebula-operator/charts
+  ```
+
+2. Update information of available charts locally from repositories.
+
+  ```bash
+  helm repo update
+  ```
+
+  For more information about `helm repo`, see [Helm Repo](https://helm.sh/docs/helm/helm_repo/).
+
+3. Create a namespace for NebulaGraph Operator.
+
+  ```bash
+  kubectl create namespace <namespace_name>
+  ```
+
+  For example, run the following command to create a namespace named `nebula-operator-system`.
+
+  ```bash
+  kubectl create namespace nebula-operator-system
+  ```
+
+  All the resources of NebulaGraph Operator are deployed in this namespace.
+
+4. Install NebulaGraph Operator.
+
+  ```bash
+  helm install nebula-operator nebula-operator/nebula-operator --namespace=<namespace_name> --version=${chart_version}
+  ```
+
+  For example, the command to install NebulaGraph Operator of version {{operator.release}} is as follows.
+
+  ```bash
+  helm install nebula-operator nebula-operator/nebula-operator --namespace=nebula-operator-system --version={{operator.release}}
+  ```
+
+  `{{operator.release}}` is the version of the nebula-operator chart. When not specifying `--version`, the latest version of the nebula-operator chart is used by default. 
+
+  Run `helm search repo -l nebula-operator` to see chart versions.
+
+  You can customize the configuration items of the NebulaGraph Operator chart before running the installation command. For more information, see [Customize installation defaults](../3.operator-management/3.1.customize-installation.md).
+
+5. View the information about the default-created CRD.
+
+  ```bash
+  kubectl get crd
+  ```
+
+  Output:
+
+  ```bash
+  NAME                                                 CREATED AT
