+# kigeon Helm Chart
+
+Deploys [kigeon](https://github.com/ninech/kigeon), a tool for sending Kubernetes events to configurable receivers.
+
+## Installation
+
+```bash
+helm repo add kigeon https://ninech.github.io/kigeon
+helm repo update
+helm install kigeon kigeon/kigeon
+```
+
+## Configuration
+
+All kigeon configuration lives under the `config` key and is rendered verbatim into a ConfigMap. See the [kigeon documentation](https://github.com/ninech/kigeon) for all available options.
+
+### Example: send events to Loki
+
+```yaml
+config:
+  eventsenders:
+    - name: loki
+      type: loki
+      config:
+        url: http://loki.monitoring.svc:3100
+```
+
+### Persistence
+
+By default, the NATS data directory uses an `emptyDir`, meaning deduplication state is lost on pod restart and kigeon may re-send events that were already forwarded. Enable persistence for production use:
+
+```yaml
+persistence:
+  enabled: true
+  size: 1Gi
+```
+
+### Passing secrets via environment variables
+
+Use `extraEnv` to inject secrets (e.g. credentials for a sender):
+
+```yaml
+extraEnv:
+  - name: LOKI_PASSWORD
+    valueFrom:
+      secretKeyRef:
+        name: loki-credentials
+        key: password
+```
+
+## Values

+|-----|---------|-------------|
+| `image.repository` | `ghcr.io/ninech/kigeon` | Image repository |
+| `image.tag` | `""` | Image tag (defaults to `.Chart.AppVersion`) |
+| `image.pullPolicy` | `IfNotPresent` | Image pull policy |
+| `serviceAccount.create` | `true` | Create a ServiceAccount |
+| `persistence.enabled` | `false` | Enable persistent storage for NATS data |

+| `persistence.storageClass` | `""` | StorageClass name (uses cluster default when empty) |
+| `persistence.existingClaim` | `""` | Use an existing PVC instead of creating one |
