# System Messages System messages are used to notify all users, similar to system announcements, and will be displayed at the top bar of the DCE 5.0 UI at specific times. ## Configure System Messages You can create a system message by applying the YAML for the system message in the [Cluster Roles](../../kpanda/user-guide/clusters/cluster-role.md). The display time of the message is determined by the time fields in the YAML. System messages will only be displayed within the time range configured by the start and end fields. 1. In the Clusters, click the name of the Global Service Cluster to enter the Gobal Service Cluster. ![cluster](../images/system-message1.png) 2. Select __CRDs__ from the left navigation bar, search for `ghippoconfig`, and click the `ghippoconfigs.ghippo.io` that appears in the search results. ![CRDs](../images/system-message2.png) 3. Click __Create from YAML__ or modify an existing YAML. ![CRDs](../images/system-message3.png) A sample YAML is as follows: ```yaml apiVersion: ghippo.io/v1alpha1 kind: GhippoConfig metadata: name: system-message spec: message: "this is a message" start: 2024-01-02T15:04:05+08:00 end: 2024-07-24T17:26:05+08:00 ```
