+# ZALENIUM-HELM-CHART
+======================================================
+
+## Introduction
+
+This chart bootstraps a zalenium deployment on a kubernetes cluster using the [Helm](https://helm.sh) package manager.
+
+## Prerequisites
+
+- Kubernetes 1.9+.
+
+## Installing the chart
+
+To install the chart with the release name `example-name`:
+
+```console
+$ helm install --name example-name teracy-incubator/zalenium
+```
+
+The command deploys Zalenium 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 `example-name` deployment:
+
+```console
+$ helm delete example-name --purge
+```
+
+The command removes all the Kubernetes components associated with the chart and deletes the release.
+
+## Configuration
+
+The following tables lists the configurable parameters of the Selenium chart and their default values.
+
+| Parameter | Description | Default |
+| --------- | ----------- | ------- |
+| `rbac.create` | If your cluster has RBAC enabled, set rbac.create to true | false |

+| `serviceAccount.create` | Set serviceAccount.create to true if you want to create an service account for zalenium | true |
+| `serviceAccount.name` | Set serviceAccount.name | zalenium |

+| `hub.image.pullPolicy` | The pull policy for the hub image | `IfNotPresent` |
+| `hub.port` | The port the hub listens on | `4444` |
+| `hub.livenessProbe.enabled` | Set hub.livenessProbe.enabled to true if you want to use livenessProbe | true |
+| `hub.readinessProbe.enabled` | Set hub.readinessProbe.enabled to true if you want to use readinessProbe | true |
+| `hub.javaOpts` | The java options for the selenium hub JVM, default sets the maximum heap size to 400 mb | `-Xmx400m -XX:+UseSerialGC` |
+| `hub.localVolumesRoot` | The root directory to store HostPath volumes (e.g. if running in minikube) | `/tmp` |
+| `hub.resources` | The resources for the hub container, defaults to minimum half a cpu and maximum 512 mb RAM | `{"limits":{"cpu":".5", "memory":"512Mi"}}` |
+| `hub.desiredContainers` | How many pods to launch at start | 2 |
+| `hub.maxDockerSeleniumContainers` | Maximum number of Selenium containers to run simultaneously | 10 |
+| `hub.sauceLabsEnabled` | Enable SauceLabs | false |
+| `hub.browserStackEnabled` | Enable BrowserStack | false |
+| `hub.testingBotEnabled` | Enable TestingBot | false |
+| `hub.videoRecordingEnabled` | Enable video recording | true |
+| `hub.cpuRequest` | CPU requested for browser pods.  The hub passes this value to the k8s API | 200m |
+| `hub.cpuLimit` | CPU limit for browser pods.  The hub passes this value to the k8s API | 400m |
+| `hub.memRequest` | Memory requested for browser pods.  The hub passes this value to the k8s API | 200Mi |

+| `hub.sendAnonymousUsageInfo` | Allows sending anonymous usage info | true |
+| `hub.sauceUserName` | Username to log into saucelabs. Use if hub.sauceLabsEnabled set to true | blank |
+| `hub.sauceAccessKey` | Access key to log into saucelabs. Use if hub.sauceLabsEnabled set to true | blank |
+| `hub.browserStackUser` | Credentials for browserstack. Use if hub.browserStackEnabled set to true | blank |

+| `mountStorage.videos.enabled` | Whether to use a videos mount volume. Set mountStorage.videos.enabled to true | true |
+| `mountStorage.data.enabled` | Whether to use a data mount volume. Set mountStorage.data.enabled to true | true |
+| `mountStorage.videos.pvcs.enabled` | Whether to use a persistent volume claim for storage. Set mountStorage.videos.pvcs.enabled to true | false |
+| `mountStorage.data.pvcs.enabled` | Whether to use a persistent volume claim for storage. Set mountStorage.data.pvcs.enabled to true | false |
+
+Specify each parameter using the `--set key0=value0,key1=value1,key..n=value..n` argument to `helm install`. For example,
+
+```console
+$ helm install --name example-name \
+  --set rbac.create=false \
+    teracy-incubator/zelenium
+```
+
+Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart.
