+# cert-manager
+
+cert-manager is a Kubernetes addon to automate the management and issuance of
+TLS certificates from various issuing sources.
+
+It will ensure certificates are valid and up to date periodically, and attempt
+to renew certificates at an appropriate time before expiry.
+
+## TL;DR;
+
+```console
+$ helm install .
+```
+
+## Introduction
+
+This chart creates a cert-manager deployment on a Kubernetes cluster using the Helm package manager.
+
+## Prerequisites
+
+- Kubernetes cluster with support for CustomResourceDefinition or ThirdPartyResource
+
+## Installing the Chart
+
+To install the chart with the release name `my-release`:
+
+```console
+$ helm install --name my-release .
+```
+
+> **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 tables lists the configurable parameters of the Drupal chart and their default values.
+
+| Parameter              | Description                             | Default                                        |

+| `replicaCount`         | Number of cert-manager replicas         | `1`                                            |

+
+Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
