+### Keptn Evaluation Definition
+A `KeptnEvaluationDefinition` is a CRD used to define evaluation tasks that can be run by the Keptn Lifecycle Controller
+as part of pre- and post-analysis phases of a workload or application.
+
+A Keptn evaluation definition looks like the following:
+
+```yaml
+apiVersion: keptn.sh/v1
+kind: KeptnEvaluationDefinition
+metadata:
+  name: my-prometheus-evaluation
+spec:
+  source: prometheus
+  objectives:
+    - name: query-1
+       query: "xxxx"
+       evaluationTarget: <20
+    - name: query-2
+       query: "yyyy"
+       evaluationTarget: >4
+```
+
+
+### Keptn Evaluation Provider
+A `KeptnEvaluationProvider` is a CRD used to define evaluation provider, which will provide data for the 
+pre- and post-analysis phases of a workload or application.
+
+A Keptn evaluation provider looks like the following:
+
+```yaml
+apiVersion: keptn.sh/v1
+kind: KeptnEvaluationProvider
+metadata:
+  name: prometheus
+spec:
+  targetServer: "http://prometheus-k8s.monitoring.svc.cluster.local:9090"
+  secretName: prometheusLoginCredentials
+```
