-Keptn is an event-driven orchestration engine for cloud-native apps.
-Started in 2018,
-it uses a declarative approach to automate delivery and operations
-so they can be scaled up to a large number of services.
-Keptn evaluates _Service Level Indicators (SLOs)_ and provides a dashboard, alerts, and auto-remediation for them.
-It also provides [integrations](https://keptn.sh/docs/integrations/)
-with the Cloud Native ecosystem 
-including _Prometheus_, _ArgoCD_, _CloudEvents_, _Backstage_,
-and many other cloud-native projects.
+
+Keptn integrates seamlessly with cloud-native deployment tools such as ArgoCD, Flux, and Gitlab to bring application
+awareness to your Kubernetes cluster. Keptn supplements the standard deployment tools with features to help you ensure
+that your deployments are in a healthy state.
+
+For information about the history of the Keptn project, see the [Keptn Lifecycle Toolkit is now Keptn!](https://medium.com/keptn/keptn-lifecycle-toolkit-is-now-keptn-e0812217bf46) blog post.
+
+Keptn includes multiple features that can be implemented independently or together.
+It targets three main use cases: Metrics, Observability, and Release lifecycle management.
