 Tool which implements [Alertmanager](https://github.com/prometheus/alertmanager) webhook notifier
-and creates Gitlab issue with the alert metadata.
+and creates Gitlab issue based on the the alert. It allows you to define own issue template using the Go template, labeling scheme
+of the resulting issue and group the alerts to a singe issue to avoid flooding yourself with identical issues.
+
+> This is probably possible in the Ultimate version of GitLab using
+> the [Prometheus integration](https://docs.gitlab.com/ee/user/project/integrations/prometheus.html#setting-up-alerts-for-prometheus-metrics-ultimate),
+> so if you have the possibility maybe first try that.
