+# SFTPGo
+
+[SFTPGo](https://github.com/drakkan/sftpgo) is a fully featured and highly configurable SFTP server with optional FTP/S and WebDAV support, written in Go. It can serve local filesystem, S3 (compatible) Object Storage, Google Cloud Storage and Azure Blob Storage.
+
+
+## TL;DR;
+
+```bash
+helm repo add skm https://charts.sagikazarmark.dev
+helm install --name sftpgo skm/sftpgo
+```
+
+
+## Introduction
+
+This chart bootstraps an [SFTPGo](https://github.com/drakkan/sftpgo) deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
+
+
+## Prerequisites
+
+- Kubernetes 1.18+
+- Helm 3.4+
+- SFTPGo 1.2.0+
+
+
+## Installing the Chart
+
+To install the chart with the release name `my-release`:
+
+```bash
+helm install --name my-release skm/sftpgo
+```
+
+> **Tip**: List all releases using `helm list`
+
+
+## Uninstalling the Chart
+
+To uninstall/delete the `my-release` deployment:
+
+```bash
+helm delete my-release
+```
+
+The command removes all the Kubernetes components associated with the chart and deletes the release.
