+This section provides comprehensive reference information about the

+[Custom Resource Definitions (CRDs)](https://kubernetes.io/docs/concepts/extend-kubernetes/api-extension/custom-resources/)
+that are defined for the Keptn Lifecycle Toolkit.

+
+Each CRD is an object of an API library.
+Keptn APIs follow the Kubernetes API versioning scheme.
+and are themselves composed of objects and sub-objects.
+By introducing CRDs, Keptn is extending the base Kubernetes API with new objects and functionality.
+Keptn APIs follow API versioning conventions recommended by Kubernetes.
+
+For more information, see the Kubernetes documentation:
+
+* [API Overview](https://kubernetes.io/docs/reference/using-api/)
+
+* [Custom Resources](https://kubernetes.io/docs/concepts/extend-kubernetes/api-extension/custom-resources/)
+
+* [API versioning](https://kubernetes.io/docs/reference/using-api/#api-versioning)
+
+* [Understanding Kubernetes Objects](https://kubernetes.io/docs/concepts/overview/working-with-objects/kubernetes-objects/)
