# Installation
-Submariner installation can be done manually using a dedicated tool, `subctl`, or Helm charts, or by using its operator. All three methods
-are described here.
+Submariner supports a number of different deployment models. An Operator is provided to manage Submariner deployments. The Operator can be
+deployed via the `subctl` CLI helper utility, or via Helm charts, or directly. Submariner can also be deployed directly, without the
+Operator, via Helm charts.
