+# DSMR-reader
+
+This is a helm chart for [DSMR-reader](https://github.com/dsmrreader/dsmr-reader).
+
+**This chart is not maintained by the upstream project and any issues with the chart should be raised [here](https://github.com/k8s-at-home/charts/issues/new/choose)**
+
+## TL;DR;
+
+```shell
+$ helm repo add k8s-at-home https://k8s-at-home.com/charts/
+$ helm install k8s-at-home/dsmr-reader
+```
+
+## Installing the Chart
+
+To install the chart with the release name `my-release`:
+
+```console
+helm install --name my-release k8s-at-home/dsmr-reader
+```
+
+## Uninstalling the Chart
+
+To uninstall/delete the `my-release` deployment:
+
+```console
+helm delete my-release --purge
+```
+
+The command removes all the Kubernetes components associated with the chart and deletes the release.
+
+## Configuration
+Read through the charts [values.yaml](https://github.com/k8s-at-home/charts/blob/master/charts/dsmr-reader/values.yaml)
+file. It has several commented out suggested values.
+Additionally you can take a look at the common library [values.yaml](https://github.com/k8s-at-home/charts/blob/master/charts/common/values.yaml) for more (advanced) configuration options.
+
+Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
+```console
+helm install dsmr-reader \
+  --set env.TZ="America/New_York" \
+    k8s-at-home/dsmr-reader
+```
+Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the
+chart. For example,
+```console
+helm install dsmr-reader k8s-at-home/dsmr-reader --values values.yaml 
+```
+
+```yaml
+image:
+  tag: ...
+```
+
+---
+**NOTE**
+
+If you get
+```console
+Error: rendered manifests contain a resource that already exists. Unable to continue with install: existing resource conflict: ...`
+```
+it may be because you uninstalled the chart with `skipuninstall` enabled, you need to manually delete the pvc or use `existingClaim`.
+
+---
+
+## Upgrading an existing Release to a new major version
+
+A major chart version change (like 4.0.1 -> 5.0.0) indicates that there is an incompatible breaking change potentially needing manual actions.
