+# Alist Helm Chart
+
+A file list program that supports multiple storages, powered by Gin and Solidjs.
+
+## Introduction
+
+This chart bootstraps alist on [Kubernetes](http://kubernetes.io) using the [Helm](https://helm.sh) package manager.
+
+## Prerequisites
+
+- Kubernetes cluster 1.20+
+- Helm v3.2.0+
+
+## Configure Alist Helm repo
+
+No Helm repository has been provided. Please `git clone` the code project, and install it manually in the `helm` directory.
+
+```bash
+git clone https://github.com/AlistGo/alist.git
+
+cd alist/helm
+```
+
+### Installing the Chart
+
+Create the alist namespace.
+
+```bash
+kubectl create namespace alist
+```
+
+Install the helm chart into the alist namespace.
+
+```bash
+helm install alist . --namespace alist
+```
+
+### Values reference
+
+The default values.yaml should be suitable for most basic deployments.
