+ntfy 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/ntfy/ntfy-docker>
+
+## Requirements
+
+Kubernetes: `>=1.16.0-0`
+
+## Dependencies
+
+| Repository | Name | Version |
+|------------|------|---------|
+| https://library-charts.k8s-at-home.com | common | 4.0.0 |
+
+## TL;DR
+
+```console
+helm repo add k8s-at-home https://k8s-at-home.com/charts/
+helm repo update
+helm install ntfy k8s-at-home/ntfy
+```
+
+## Installing the Chart
+
+To install the chart with the release name `ntfy`
+
+```console
+helm install ntfy k8s-at-home/ntfy
+```
+
+## Uninstalling the Chart
+
+To uninstall the `ntfy` deployment
+
+```console
+helm uninstall ntfy
+```
+
+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 ntfy \
+  --set env.TZ="America/New York" \
+    k8s-at-home/ntfy
+```
+
+Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart.
+
+```console
+helm install ntfy k8s-at-home/ntfy -f values.yaml
+```
+
+## Custom configuration
+
+N/A
+
+## Values
+
+**Important**: When deploying an application Helm chart you can add more values from our common library chart [here](https://github.com/k8s-at-home/library-charts/tree/main/charts/stable/common)
+
+| Key | Type | Default | Description |
