+## Alerting overview
+
+Grafana-Zabbix plugin introduces [alerting](https://grafana.com/docs/grafana/latest/alerting/) feature support in 4.0 release. Work still in progress, so current alerting support has some limitations:
+
+- Only `Metrics` query mode supported.
+- Queries with data processing functions are not supported.
+
+## Creating alerts
+
+In order to create alert, open panel query editor and switch to the `Alert` tab. Click `Create Alert` button, configure alert and save dashboard. Refer to [Grafana](https://grafana.com/docs/grafana/latest/alerting/create-alerts/) documentation for more details about alerts configuration.
