• Create a slack app and an incoming webhook following these instructions.
• Navigate to Contact points tab in the Alerting section of the Grafana instance.
• Click on Add contact point, give a name to the contact point and select Slack from the Integration drop down.
• Add the webhook created from the first step under the Webhook URL option.
• Add the following snippet under the Title option in the Optional Slack settings section:

[{{ .Status | toUpper }}{{ if eq .Status "firing" }}:{{ .Alerts.Firing | len }}{{ end }}] {{ if .CommonLabels.cluster }}[{{ .CommonLabels.cluster }}]{{ end }} {{ .CommonLabels.alertname }}

• Add the following snippet under the Text Body option in the Optional Slack settings section:

           {{ with index .Alerts 0 -}}
        :chart_with_upwards_trend: *<{{ .GeneratorURL }}|Graph>*
        {{- if .Annotations.runbook }}   :notebook: *<{{ .Annotations.runbook }}|Runbook>*{{ end }}
      {{ end }}
  *Alert details:*

While this standard alert template should be sufficient for most use-cases, you can also customize the alert template using the Grafana documentation.
