+# Neolink
+
+This is a helm chart for [Neolink](https://github.com/thirtythreeforty/neolink).
+
+**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/neolink
+```
+
+## Installing the Chart
+
+To install the chart with the release name `my-release`:
+
+```console
+helm install my-release k8s-at-home/neolink
+```
+
+## 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
+The chart's [values.yaml](https://github.com/k8s-at-home/charts/blob/master/charts/neolink/values.yaml) file contains a set of suggested values for a minimal deployment. Further configuration options are found in the [common library](https://github.com/k8s-at-home/charts/blob/master/charts/common/values.yaml).
+
+The configuration for the application itself is set as a configmap and mounted in the container as /etc/neolink.toml. Refer to the sample config [here.](https://github.com/thirtythreeforty/neolink/blob/master/sample_config.toml)
+
+
+Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
+```console
+helm install neolink \
+  --set env.TZ="America/New_York" \
+    k8s-at-home/neolink
+```
+Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
+```console
+helm install neolink k8s-at-home/neolink --values values.yaml
+```
