+### Keptn Lifecycle Toolkit Components
+
+The Keptn Lifecycle Toolkit consists of two main components:
+
+* Keptn Lifecycle Operator, which splits into two separate operators
+in Release 0.7.0 and later:
+  * Lifecycle-Operator
+  * Metrics-Operator
+* Keptn Lifecycle Scheduler

+
+**Keptn's Lifecycle Operator** is
+a Kubernetes [operator](https://kubernetes.io/docs/concepts/extend-kubernetes/operator/)
+that automates the deployment and management
+of the Keptn Lifecycle Controller components in a Kubernetes cluster.
+The Keptn Lifecycle Operator contains several controllers for **Keptn CRDs**
+and a **Mutating Webhook**.
+
+Here's a brief overview:
+
+**Keptn CRDs:** Keptn Lifecycle Operator contains
+several controllers that manage and reconcile different types of Keptn CRDs
+such as the Project Controller, Service Controller, and Stage Controller.
+
+**Mutating Webhook:** automatically injects Keptn labels
+and annotations into Kubernetes resources,
+such as deployments and services.
+These labels and annotations are used to enable Keptn's automation
+and monitoring capabilities.
+
+**Keptn's Lifecycle Metrics Operator**
+collects,  processes, and analyzes metrics data from a variety of sources.
+Once collected, this data, can be used to generate a variety of reports
+and dashboards that provide insights into the health and performance of the application and infrastructure.
+
+**Keptn's Lifecycle Scheduler** replaces the
+[Kubernetes scheduler](https://kubernetes.io/docs/concepts/scheduling-eviction/kube-scheduler/)
+to allow users to schedule events and tasks to occur
+at specific times during the application lifecycle.
+The Lifecycle Scheduler can trigger events such as
+deployment, testing, and remediation at specific times or intervals.
+The Keptn Scheduler guarantees that Pods are initiated only after
+the Pre-Deployment checks are completed.
