+Helm charts for the Fuseki deployment of Lock-Unlock with Subgraph strategy
+
+**Homepage:** <https://labs.kadaster.nl/cases/lockunlock>
+
+## Source Code
+
+* <https://github.com/kadaster-labs/secured-sparql-endpoint-subgraph>
+
+## Get Repo Info
+```console
+helm repo add lock-unlock https://kadaster-labs.github.io/lock-unlock-helm-charts/
+helm repo update
+```
+
+## Install Chart
+```console
+helm install [RELEASE_NAME] lock-unlock/lock-unlock-subgraph
+```
+
+The command deploys lock-unlock-subgraph on the Kubernetes cluster in the default configuration.
+
+> [!IMPORTANT]
+> The Helm chart doesn't work as is, as the default container registry isn't publicly accessible. Please contact our team to get information about the required `imagePullSecrets` configuration, or build the images yourself. The charts accommodate setting your own registry.
+
+_See [configuration](#configuration) below._
+
+## Uninstall Chart
+```console
+helm uninstall [RELEASE_NAME]
+```
+
+This removes all the Kubernetes components associated with the chart and deletes the release.
+
+## Upgrading Chart
+```console
+helm upgrade [RELEASE_NAME] [CHART] --install
+```
+
+## Configuration
+To see all configurable options with detailed comments, visit the chart's values.yaml, or run these configuration commands:
+
+```console
+helm show values lock-unlock/lock-unlock-subgraph
+```
+
+It is required to either set the `imagePullSecrets`, or build the images yourself and supply your own container registry. Instructions on how to create a Secret by providing credentials on the command line can be found [here](https://kubernetes.io/docs/tasks/configure-pod-container/pull-image-private-registry/#create-a-secret-by-providing-credentials-on-the-command-line).
+
+### Resources
+The Java VM requires at least 2Gi of memory to function properly, so the Helm deployment uses this as default. You may change this value as desired.
