+language-tool helm package
+
+**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)**
+
+## Source Code
+
+* <https://github.com/language-tool/language-tool-docker>
+
+## Requirements
+
+Kubernetes: `>=1.16.0-0`
+
+## Dependencies
+
+| Repository | Name | Version |
+|------------|------|---------|
+| https://library-charts.k8s-at-home.com | common | 4.5.2 |
+
+## TL;DR
+
+```console
+helm repo add k8s-at-home https://k8s-at-home.com/charts/
+helm repo update
+helm install language-tool k8s-at-home/language-tool
+```
+
+## Installing the Chart
+
+To install the chart with the release name `language-tool`
+
+```console
+helm install language-tool k8s-at-home/language-tool
+```
+
+## Uninstalling the Chart
+
+To uninstall the `language-tool` deployment
+
+```console
+helm uninstall language-tool
+```
+
+The command removes all the Kubernetes components associated with the chart **including persistent volumes** and deletes the release.
+
+## Configuration
+
+Read through the [values.yaml](./values.yaml) file. It has several commented out suggested values.
+Other values may be used from the [values.yaml](https://github.com/k8s-at-home/library-charts/tree/main/charts/stable/common/values.yaml) from the [common library](https://github.com/k8s-at-home/library-charts/tree/main/charts/stable/common).
+
+Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`.
+
+```console
+helm install language-tool \
+  --set env.TZ="America/New York" \
+    k8s-at-home/language-tool
+```
+
+Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart.
+
+```console
+helm install language-tool k8s-at-home/language-tool -f values.yaml
+```
+
+## Custom configuration
+
+N/A
+
