+## Usage
+
+[Helm](https://helm.sh) must be installed to use the charts.  Please refer to
+Helm's [documentation](https://helm.sh/docs) to get started.
+
+Once Helm has been set up correctly, add the repo as follows:
+
+  helm repo add rstuf https://repository-service-tuf.github.io/helm-charts
+
+If you had already added this repo earlier, run `helm repo update` to retrieve
+the latest versions of the packages.  You can then run `helm search repo
+rstuf` to see the charts.
+
+To install the rstuf chart:
+
+    helm install my-rstuf rstuf/rstuf
+
+To uninstall the chart:
+
+    helm delete my-rstuf
