+### Standalone Vald agent NGT deployment
+
+Each component can be disabled by setting the value `false` to the `[component].enabled` field.
+This is useful for deploying only Vald agent NGT pods.
+
+There is an example yaml [values-agent-ngt-standalone.yaml][agent-ngt-standalone-yaml] to deploy standalone agent NGT.
+Please run the following command to install the chart with this values yaml,
+
+    $ helm repo add vald https://vald.vdaas.org/charts
+    $ helm install --values values-agent-ngt-standalone.yaml vald-agent-ngt vald/vald
+
+agent-ngt-standalone-yaml: ./values-agent-ngt-standalone.yaml
