+# Kubernetes / Helm Charts
+
+If you are using Kubernetes, you can use the [helm charts](https://helm.sh/) provided in this [repository](https://github.com/Part-DB/helm-charts).
+
+## Usage
+
+[Helm](https://helm.sh) must be installed to use the charts.  Please refer to
+Helm's [documentation](https://helm.sh/docs) to get started.
+
+Once Helm has been set up correctly, add the repo as follows:
+
+`helm repo add part-db https://part-db.github.io/helm-charts`
+
+If you had already added this repo earlier, run `helm repo update` to retrieve
+the latest versions of the packages.  You can then run `helm search repo
+part-db` to see the charts.
+
+To install the part-db chart:
+
+    helm install my-part-db part-db/part-db
+
+To uninstall the chart:
+
+    helm delete my-part-db
+
+This repository is also available at [ArtifactHUB](https://artifacthub.io/packages/search?repo=part-db).
+
+## Configuration
+
+See the README in the [chart directory](https://github.com/Part-DB/helm-charts/tree/main/charts/part-db) for more
+information on the available configuration options.
+
+## Bugreports
+
+If you find issues related to the helm charts, please open an issue in the [helm-charts repository](https://github.com/Part-DB/helm-charts).
