 ## Cmd Usage
 
-The CLI can be used to :
-- Deploy dashboards and alerts to grafana
-- Generate JSON from dashboards defined in the `dashboards` folder
+CLI to manipulate grafana resources
+
+### Contact Point
 
-`func NewDashboard(props *Props)` in each [dashboards](./dashboards) packages is called from [cmd](./cmd/builder.go) to deploy or generate JSON from the dashboard.
+#### List
 
-Example to deploy a dashboard to grafana instance using URL and token:
 ```shell
-make build
-./observability-lib deploy \
-  --dashboard-name DashboardName \
-  --dashboard-folder FolderName \
-  --grafana-url $GRAFANA_URL \
-  --grafana-token $GRAFANA_TOKEN \
-  --type core-node \
-  --platform kubernetes \
-  --metrics-datasource Prometheus
+./observability-lib api contact-point list \
+  --grafana-url http://localhost:3000 \
+  --grafana-token <token>
 ```
-To see how to get a grafana token you can check this [page](https://grafana.com/docs/grafana/latest/administration/service-accounts/)
 
-Example to generate JSON from a dashboard defined in the `dashboards` folder:
+#### Delete
+
 ```shell
-make build

+### Notification Policy
+
+#### List
+
+```shell
