+#### Managed Service: Landscaper
+
+Landscaper manages the installation, updates, and uninstallation of cloud-native workloads, with focus on larger complexities, while being capable of handling complex dependency chains between the individual components.
+
+To install a Landscaper for your MCP, you need to create a `Landscaper` resource with the same namespace and name as your `ManagedControlPlane`. The following example installs the Landscaper with default configuration.
+
+```yaml
+apiVersion: landscaper.services.openmcp.cloud/v1alpha1
+kind: Landscaper
+metadata:
+  name: mcp-01 # Same name as your ManagedControlPlane
+  namespace: project-platform-team--ws-dev # Same namespace as your ManagedControlPlane
