+# Argo Events
+
+[Argo Events](https://argoproj.github.io/argo-events/) is an open source container-native event-driven workflow automation framework for Kubernetes which helps you trigger K8s objects, Argo Workflows, Serverless workloads, etc. on events from a variety of sources. Argo Events is implemented as a Kubernetes CRD (Custom Resource Definition).
+
+## Usage
+
+Argo Events can be deployed by enabling the add-on via the following.
+
+```hcl
+enable_argo_events = true
+```
+
+You can optionally customize the Helm chart that deploys Argo Events via the following configuration.
+
+```hcl
+  enable_argo_events = true
+
+  argo_events = {
+    name          = "argo-events"
+    chart_version = "2.4.0"
+    repository    = "https://argoproj.github.io/argo-helm"
+    namespace     = "argo-events"
+    values        = [templatefile("${path.module}/values.yaml", {})]
+  }
+
+```
+
+Verify argo-events pods are running.
+
+```sh
+$ kubectl get pods -n argo-events
+NAME                                                  READY   STATUS    RESTARTS   AGE
+argo-events-controller-manager-bfb894cdb-k8hzn        1/1     Running   0          11m
+```
