+# A self-hosted data logger for your Tesla 🚘
+
+This is an opinionated helm chart for [Teslamate](https://github.com/adriankumpf/teslamate) installed with a standalone postgresql database.
+
+The default values and container images used in this chart will allow for running in a multi-arch cluster (amd64, arm, arm64)
+
+## TL;DR;
+
+```shell
+$ helm repo add billimek https://billimek.com/billimek-charts/
+$ helm install billimek/teslamate
+```
+
+## Installing the Chart
+
+To install the chart with the release name `my-release`:
+
+```console
+helm install --name teslamate billimek/teslamate
+```
+
+## Uninstalling the Chart
+
+To uninstall/delete the `teslamate` deployment:
+
+```console
+helm delete teslamate --purge
+```
+
+The command removes all the Kubernetes components associated with the chart and deletes the release.
+
+## Configuration
+
+Read through the [values.yaml](https://github.com/billimek/billimek-charts/blob/master/teslamate/values.yaml) file. It has several commented out suggested values.
+
+Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
+
+```console
+helm install --name teslamate \
+  --set timeZone="America/New York" \
+    billimek/teslamate
+```
+
+Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
+
+```console
+helm install --name teslamate -f values.yaml stable/teslamate
+```
