       --metric-allowlist string          Comma-separated list of metrics to be exposed. This list comprises of exact metric names and/or regex patterns. The allowlist and denylist are mutually exclusive.
       --metric-denylist string           Comma-separated list of metrics not to be enabled. This list comprises of exact metric names and/or regex patterns. The allowlist and denylist are mutually exclusive.
-      --namespace string                 Comma-separated list of namespaces to be enabled. Defaults to ""
+      --namespaces string                Comma-separated list of namespaces to be enabled. Defaults to ""
       --pod string                       Name of the pod that contains the kube-state-metrics container. When set, it is expected that --pod and --pod-namespace are both set. Most likely this should be passed via the downward API. This is used for auto-detecting sharding. If set, this has preference over statically configured sharding. This is experimental, it may be removed without notice.
