+# Alert Operator Chart
+
+This repository provide a k8s prometheus alert-operator chart.
+
+## TL;DR
+To install:
+```bash
+helm upgrade --install -n alert-operator .
+```
+
+## Chart Content
+The chart will provide the following resources:
+1. Alert Operator CRD's resource (installed first using helm CRD hook)
+2. Alert operator supporting service-account, cluster-role and cluster-role-binding resources.
+3. Alert-operator deployment
+4. Alert-operator service,  ServiceMonitor & monitoring resources. *** currently disabled by default as prometheus metrics are not yet supported ***
+
+## alert-operator Configuration
+The following values are set in this chart values.yaml, some overwrite the sub-chart values
+
+
+### k8s-kube2iam Chart Configuration
+
+| Parameter     | Description | Default  |
+| ------------- | ------------- | --------|
+| replicaCount  | The deployment replace count | 1 |
+| image.repository  | The container image repository | georgedriver/alertroute-operator  |
+| nameOverride   |  A name to overide chart name. | ''  |
+| fullnameOverride   | A full name to be used with chart resources  | ''  |
+| service.port   |  The port to expose for metrics |  60000 |
+|  monitoring.enabled  | Enable monitoring resources  |  false |
+|  monitoring.alerting.enables  | Enable alerting resources  |  false |
+| resources   | Resource limit/request for deployment  | {}  |
+| nodeSelector   | Node selector label lists  | {}  |
+|tolerations   | tolerations label list  | []  |
+| affinity   | affinity label list  |  {} |
+| imagePullSecrets   | list of existing pull secret to use with the container  |  [] |
+| crd.install   | If set, the helm will add the CRD's (Set to true only on new clusters)  | 'false'  |
+
+## Monitoring
+
+### Service Monitor Resource
+When monitoring enabled, a ServiceMonitor will be created to auto-add the alert-operator metrics to Prometheus. Check the Prometheus Operator Service Monitor for details.
+
+## Grafana Dashaboard
+When monitoring enabled, Helm will create a config map resources with the label of "grafana-dashboard" to store alert-operator dashboards.
+If you want to add a new dashboard, create the dashboard, export it to a JSON file and put it in the "dashboards" folder under the charts.
+Grafana will auto-detect any dashboard based on the label, and load it.
+
+## Prometheus Rules
+PrometheusRules resource is used to create Prometheus alerts. If alerting enabled, helm will create the resource for Prometheus to auto-detect it.
+To create/modify alerts - edit the PrometheusRules resource file in the templates folder and change the spec. See Prometheus documantation for more details on alerts.
+
+## Alert Manager
+AlertManager resource will handle spinning a new instance of alertmanager for your application.
+Use alert manager resource, and it's Configuration to set how your alerts are being handled - if you want to push them to Pagerduty/email/slack etc.
+See Prometheus Alert Manager documantation for more details
