+
+[role="_abstract"]
+You can install {gitops-title} Operator from the OperatorHub using the CLI.
+
+.Procedure
+
+. Create a Subscription object YAML file to subscribe a namespace to the {gitops-title}, for example, `sub.yaml`:
++
+.Example Subscription
+[source,yaml]
+----
+apiVersion: operators.coreos.com/v1alpha1
+kind: Subscription
+metadata:
+  name: openshift-gitops-operator
+  namespace: openshift-operators
+spec:
+  channel: stable <1>
+  installPlanApproval: Automatic
+  name: openshift-gitops-operator <2>
+  source: redhat-operators <3>
+  sourceNamespace: openshift-marketplace <4> 
+----
+<1> Specify the channel name from where you want to subscribe the Operator.
+<2> Specify the name of the Operator to subscribe to.
+<3> Specify the name of the CatalogSource that provides the Operator.
+<4> The namespace of the CatalogSource. Use `openshift-marketplace` for the default OperatorHub CatalogSources.
++
+. Apply the `Subscription` to the cluster:
++
+[source,terminal]
+----
+$ oc apply -f openshift-gitops-sub.yaml
+----
+. After the installation is complete, ensure that all the pods in the `openshift-gitops` namespace are running:
++
+[source,terminal]
+----
+$ oc get pods -n openshift-gitops
+----
+.Example output
