+A Helm chart for the calert which uses Alertmanager webhook receiver to receive alerts payload, and pushes this data to Google Chat webhook endpoint.
+
+**Homepage:** <https://github.com/mr-karan/calert>
+
+## Alertmanager Integration
+
+The Alertmanager helm chart can be found [here](https://github.com/prometheus-community/helm-charts/tree/main/charts/alertmanager). You can refer to the following config block to route webhook alerts to `calert`:
+
+```yml
+config:
+  receivers:
+    - name: 'calert'
+      webhook_configs:
+      - url: 'http://calert:6000/dispatch'
+
+  route:
+    receiver: 'calert'
+    group_wait: 30s
+    group_interval: 60s
+    repeat_interval: 3h
+    group_by: ['alertname']
+```
