+# Kyverno
+
+Kyverno is a policy engine that can help kubernetes clusters to enforce security and governance policies.
+
+This addon provides support for:
+1. [Kyverno](https://github.com/kyverno/kyverno/tree/main/charts/kyverno)
+2. [Kyverno policies](https://github.com/kyverno/kyverno/tree/main/charts/kyverno-policies)
+3. [Kyverno policy reporter](https://github.com/kyverno/policy-reporter/tree/main/charts/policy-reporter)
+
+## Usage
+
+Kyverno can be deployed by enabling the respective add-on(s) via the following.
+
+```hcl
+enable_kyverno                 = true
+enable_kyverno_policies        = true
+enable_kyverno_policy_reporter = true
+```
+
+### GitOps Configuration
+
+The following properties are made available for use when managing the add-on via GitOps.
+
+```sh
+kyverno = {
+  enable = true
+}
+
+kyverno_policies = {
+  enable = true
+}
+
+kyverno_policy_reporter = {
+  enable = true
+}
+```
