+# Getting Started
+
+## Prerequisites
+
+- A NetBird [service user access token](https://docs.netbird.io/manage/public-api).
+- Access to Kubernetes cluster.
+- Kubectl and Helm installed locally.
+
+## Steps
+
+Add the Helm repository.
+
+```sh
+helm repo add netbirdio https://netbirdio.github.io/kubernetes-operator
+```
+
+Install cert-manager, it is recommended so the Kubernetes API can communicate with the operator's admission webhooks. Skip this step if you already have cert-manager installed.
+
+```sh
+kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.17.0/cert-manager.yaml
+```
+
+Create the NetBird namespace and API secret. The operator needs a NetBird personal access token to authenticate with the NetBird Management API.
+
+```sh
+kubectl create namespace netbird
+kubectl -n netbird create secret generic netbird-mgmt-api-key --from-literal=NB_API_KEY=${ACCESS_TOKEN}
+```
+
+Install the Netbird operator.
+
+```sh
+helm install netbird-operator netbirdio/kubernetes-operator --create-namespace --namespace netbird
+```
+
+Verify the installation. All pods should be in a `Running` state before continuing.
+
+```sh
+kubectl get pods -n netbird
+```
+
+Once the operator is running, see the [usage guide](/docs/usage.md) to start exposing services to your NetBird network.
