+If the Kyma environemnt is requested, the variable `kyma_administrators` in the [variables.tf](./variables.tf) file must be filled with the users that should be assigned as administrators. This condition is validated

 ### Output
 
 The output defined in the [outputs.tf](./outputs.tf) file returns the main information relevant for the development team namely:
 
 - a link to the subaccount
-- The ID of the Cloud Foundry org
-- The API endpoint of the Cloud Foundry environment
-
-
+- The ID of the Cloud Foundry org if a Cloud Foundry environment is created
+- The API endpoint of the Cloud Foundry environment if a Cloud Foundry environment is created
+- The URL to the Kyma dashboard if a Kyma environment is created
+- The URL to the Kubeconfig file for the Kyma runtime if a Kyma environment is created

+# SAP BTP - Kyma Environment Setup
+
+This module encapsulates the creation of a Kyma environment in a subaccount on SAP BTP. The configuration is a basic setup. In a real world scenario, you would likely want to customize the setuo further with resoect to the available parameters like machine type etc. as described in the [documentation](https://help.sap.com/docs/btp/sap-business-technology-platform/provisioning-and-update-parameters-in-kyma-environment) depending on the stage of the environment (development, test, production).
