+# Restic Rest Server
+
+[Restic](https://restic.net) is a backup program that fast, secure, and efficient. [Restic Rest Server](https://github.com/restic/rest-server) is a high performance HTTP server that implements restic's REST backend API.
+
+## Introduction
+
+## Prerequisites
+
+## Installing the Chart
+
+Make sure you have the repository enabled, then install the `rest-server` chart.
+
+```shell script
+helm repo add edjmao https://edjmao.github.io/charts/pkg
+helm repo update
+helm install edjmao/rest-server
+```
+
+## Configuration
+
+By default, this chart does not provide persistent storage, so any backups made to the system will be saved to an `emptyDir` volume. It is recommended that you enable persistent storage to ensure that your data is backed up safely.
+
+The following table lists common configurable parameters of the chart and their default values. See values.yaml for all available options.
+
+| Parameter | Description | Default |
+| --------------------------------------- | --------------------------------------------------------------------------- | ------------------------------------ |
+| `image.pullPolicy` | Container pull policy | `IfNotPresent` |
+| `image.repository` | Container image to use | `restic/rest-server` |
+| `image.tag` | Container image tag to deploy | `0.9.7` |
+| `persistence.enabled` | Whether to use a PVC for persistent storage | `false` |
+| `persistence.existingClaim` | The name of a PVC to use | `""` |
+| `persistence.subPath` | If set, mount the subdirectory as the root for backups. Useful for PVCs handling multiple instances.| `""` |
+| `service.type` | Kubernetes Service type | `ClusterIP` |
+| `service.clusterIP` | Static clusterIP or None for headless services | `nil` |
+| `options.disableAuthentication` | Disable HTTP basic authentication | `false` |
+| `ingress.enabled` | Enable ingress controller resource | `false` |
+| `ingress.annotations` | Ingress annotations | `[]` |
+| `ingress.labels` | Ingress labels | `[]` |
+| `ingress.hosts[0].host` | Hostname for the ingress | `` |
+| `ingress.hosts[0].path` | Path within the url structure | `` |
+| `ingress.tls[0].secretName` | Name of the secret for the TLS cert | `` |
+| `ingress.tls[0].hosts` | List of hostnames for the TLS cert | `[]` |
+
+## Authentication and User Accounts
+
+HTTP Basic Auth is enabled by default. This requires a user to be created to be able to access the server. Create the user by executing the following:
+
+```shell script
+$ kubectl exec -it restic-rest-server-xxxxxxxxxx-xxxxx create_user <username>
+```
+
+This will prompt you for a new password. To run restic with basic auth, include it between the protocol and URL.
+
+```shell script
+$ restic init -r rest:https://username:password@my-restic-host/my-repo
+```
+
+The user shall be saved in the `.htpasswd` file in the PVC and will persist across deployments (if persistence is enabled).
+
+To disable basic auth, set `options.disableAuthentication` to `true`.
