+# Argo CD ApplicationSet Chart
+
+A Helm chart for Argo CD ApplicationSet, a controller to programmatically generate Argo CD Application.
+
+Source code can be found [here](https://github.com/argoproj-labs/applicationset/)
+
+## Additional Information
+
+This is a **community maintained** chart. This chart installs the [applicationset](https://github.com/argoproj-labs/applicationset) controller.
+
+This chart currently installs the non-HA version of Argo CD ApplicationSet.
+
+## Installing the Chart
+
+To install the chart with the release name `my-release`:
+
+```console
+$ helm repo add argo https://argoproj.github.io/argo-helm
+"argo" has been added to your repositories
+
+$ helm install --name my-release argo/argo-applicationset
+NAME: my-release
+...
+```
+
+### Helm v3 Compatibility
+
+Users of Helm v3 should set the `installCRDs` value to `false` to avoid warnings about nonexistent webhooks.
+
