+## Introduction
+
+The Gaia-X OCM Tenant Manager is designed to facilitate the management of tenants in the Gaia-X ecosystem. It allows users to create, update, and delete tenants, as well as manage their associated resources.
+
+## Features
+
+- Create new tenants
+- Update existing tenants
+- Delete tenants
+- Manage tenant resources
+
+## Installation
+
+To install the Gaia-X OCM Tenant Manager, follow these steps:
+
+1. Clone the repository:
+
+   ```bash
+   git clone https://github.com/gaia-x/ocm-tenant-manager.git

+description: OCM Tenant Manager Helm chart
+
+# A chart can be either an 'application' or a 'library' chart.
+#
+# 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.
+type: application
+
+# This is the chart version. This version number should be incremented each time you make changes
+# to the chart and its templates, including the app version.
+# Versions are expected to follow Semantic Versioning (https://semver.org/)
+version: 1.1.0
+
+# This is the version number of the application being deployed. This version number should be
+# incremented each time you make changes to the application. Versions are not expected to
+# follow Semantic Versioning. They should reflect the version the application is using.
+# It is recommended to use it with quotes.
