+# Palworld Helm Chart
+
+Allows you to deploy the usage of [Palworld Server docker](https://github.com/Filipe-Souza/palworld-server-docker) as
+a helm chart and with helm deployments.
+
+This is an advanced method of installation and can be quite difficult to non-technical trying to set it up.
+
+## Dependencies
+
+You will need the [Helm client](https://helm.sh/docs/intro/install/) and a Kubernetes cluster.
+
+## Install the chart
+
+There is no helm package available yet, so you need to clone this repo and setup it manually, or with some GitOps tool
+like ArgoCD/FluxCD.
+
+After cloning the repository, you can create a new file, e.g.: values.override.yaml to store your custom values.
+
+After copying, modify your values.override.yaml as needed. You can look up the
+[values summary](VALUES_SUMMARY.md) to see the parameter documentation.
+
+After that, you can apply the chart:
+
+```bash
+helm install --create-namespace --namespace palworld palworld chart/ --values values.override.yaml
+```
+
+You can remove all the resources created (except the PVC) with the following command:
+
+```bash
+helm uninstall -n palworld palworld
+```
