+# Garage helm3 chart
+
+This chart deploys garage on a kubernetes cluster.
+
+## Deploying
+
+With default options:
+
+```bash
+helm install --create-namespace --namespace garage garage ./garage
+```
+
+With custom values:
+
+```bash
+helm install --create-namespace --namespace garage garage ./garage -f values.override.yaml
+```
+
+## Overriding default values
+
+All possible configuration values can be found in [values.yaml](garage/values.yaml).
+
+This is an example `values.overrride.yaml` for deploying in a microk8s cluster with a https s3 api ingress route:
+
+```yaml
+# Start 4 instances (StatefulSets) of garage
+replicaCount: 4
+
+# Override default storage class and size
+persistence:
+  meta:
+    storageClass: "openebs-hostpath"
+    size: 100Mi
+  data:
+    storageClass: "openebs-hostpath"
+    size: 1Gi
+
+ingress:
+  s3:
+    api:
+      enabled: true
+      className: "public"
+      annotations:
+        cert-manager.io/cluster-issuer: "letsencrypt-prod"
+        nginx.ingress.kubernetes.io/proxy-body-size: 500m
+      hosts:
+        - host: s3-api.my-domain.com
+          paths:
+            - path: /
+              pathType: Prefix
+      tls:
+        - secretName: garage-ingress-cert
+          hosts:
+            - s3-api.my-domain.com
+```
+
+## Removing
+
+```bash
+helm delete --namespace garage garage
+```
+
+Note that this will leave behind custom CRD `garagenodes.deuxfleurs.fr`, which must be removed manually if desired.

+# Library charts provide useful utilities or functions for the chart developer. They're included as
