 ---
 Each execution of a model resource (BPMN, DMN, and CMMN) generates historic data during execution that is stored in the database. The Camunda 7 History Cleanup removes this historic data from the database based on the HTTL (History Time To Live) defined. If using the History Cleanup in Camunda 7 the HTTL must be defined in one of the following ways:
 - Define HTTL per model directly in the Camunda Modeller
-- Set a default HTTL for the engine that is applied to all deployed model resources on the engine
-- Switch off the HTTL check for the deployment if History Cleanup is not used
+- Set a default HTTL via an engine configuration that is applied to all deployed model resources on the engine
+- Switch off the HTTL check via an engine configuration if History Cleanup is not used
