+# Application charts are a collection of templates that can be packaged into versioned archives
+# to be deployed.
+#
+# Library charts provide useful utilities or functions for the chart developer. They're included as
+# a dependency of application charts to inject those utilities and functions into the rendering
+# pipeline. Library charts do not define any templates and therefore cannot be deployed.

+
+[code-server](https://github.com/cdr/code-server) code-server is VS Code running
+on a remote server, accessible through the browser.
+
+## TL;DR;
+
+```console
+$ git clone https://github.com/cdr/code-server.git
+$ helm install deployment/chart
+```
+
+## Introduction
+
+This chart bootstraps a code-server deployment on a
+[Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh)
+package manager.
+
+## Prerequisites
+
+  - Kubernetes 1.6+
+
+## Installing the Chart
+
+To install the chart with the release name `my-release`:
+
+```console
+$ helm install --name my-release deployment/chart
+```
+
+The command deploys code-server on the Kubernetes cluster in the default
+configuration. The [configuration](#configuration) section lists the parameters
+that can be configured during installation.
+
+> **Tip**: List all releases using `helm list`
+
+## Uninstalling the Chart
+
+To uninstall/delete the `my-release` deployment:
+
+```console
+$ helm delete my-release
+```
+
+The command removes all the Kubernetes components associated with the chart and
+deletes the release.
+
+## Configuration
+
+The following table lists the configurable parameters of the nginx-ingress chart
+and their default values.

+
+The following table lists the configurable parameters of the code-server chart
+and their default values.
+
+## Values
+
+| Key | Type | Default | Description |
+|-----|------|---------|-------------|
+| affinity | object | `{}` |  |
+| extraArgs | list | `[]` |  |
+| extraConfigmapMounts | list | `[]` |  |
+| extraContainers | string | `""` |  |
+| extraSecretMounts | list | `[]` |  |
+| extraVars | list | `[]` |  |
+| extraVolumeMounts | list | `[]` |  |
+| fullnameOverride | string | `""` |  |
+| hostnameOverride | string | `""` |  |
+| image.pullPolicy | string | `"Always"` |  |
+| image.repository | string | `"codercom/code-server"` |  |
+| image.tag | string | `"3.5.0"` |  |
+| imagePullSecrets | list | `[]` |  |
+| ingress.enabled | bool | `false` |  |
+| nameOverride | string | `""` |  |
+| nodeSelector | object | `{}` |  |
+| persistence.accessMode | string | `"ReadWriteOnce"` |  |
+| persistence.annotations | object | `{}` |  |
+| persistence.enabled | bool | `true` |  |
+| persistence.size | string | `"1Gi"` |  |
+| podAnnotations | object | `{}` |  |
+| podSecurityContext | object | `{}` |  |
+| replicaCount | int | `1` |  |
+| resources | object | `{}` |  |
+| securityContext.enabled | bool | `true` |  |
+| securityContext.fsGroup | int | `1000` |  |
+| securityContext.runAsUser | int | `1000` |  |
+| service.port | int | `8443` |  |
+| service.type | string | `"ClusterIP"` |  |
+| serviceAccount.create | bool | `true` |  |
+| serviceAccount.name | string | `nil` |  |
+| tolerations | list | `[]` |  |
+| volumePermissions.enabled | bool | `true` |  |
+| volumePermissions.securityContext.runAsUser | int | `0` |  |
+
+Specify each parameter using the `--set key=value[,key=value]` argument to `helm
+install`. For example,
+
+```console
+$ helm install --name my-release \
+  --set persistence.enabled=false \
+    deployment/chart
+```
+
+The above command sets the the persistence storage to false.
+
+Alternatively, a YAML file that specifies the values for the above parameters
+can be provided while installing the chart. For example,
+
+```console
+$ helm install --name my-release -f values.yaml deployment/chart
+```
+
+> **Tip**: You can use the default [values.yaml](values.yaml)
+
