toc::[]

`kn` enables simple interaction with Knative components on {product-title}.

You can enable Knative on {product-title} by installing {ServerlessProductName}. For more information, see the documentation on xref:../serverless/serverless-getting-started.adoc#serverless-getting-started[Getting started with {ServerlessProductName}].

[NOTE]
====
{ServerlessProductName} cannot be installed using the `kn` CLI. A cluster administrator must install the {ServerlessOperatorName} and set up the Knative components, as described in the xref:../serverless/installing_serverless/installing-openshift-serverless.adoc#installing-openshift-serverless[Serverless applications] documentation for {product-title}.
====

== Key features
`kn` is designed to make serverless computing tasks simple and concise.
Key features of `kn` include:

* xref:../serverless/serving-creating-managing-apps.adoc#serving-creating-managing-apps[Deploy serverless applications] from the command line.
* Manage features of Knative Serving, such as services, revisions, and traffic-splitting.
// TODO: add docs about revisions

* Extend `kn` with flexible plugin architecture, similar to `kubectl`.
// * Easily integrate {ServerlessProductName} with OpenShift Pipelines by using `kn` in an OpenShift Pipelines task
// TODO: Add integrations later when we have docs about this.
// TODO: add docs about these deployment types?
