+# Management API
+
+## Overview
+The Management API is a RESTful API that enables to perform Create/Read/Update/Delete operations for provisioning targets (i.e. devices) and repository content (i.e. software). Based on the Management API you can manage and monitor software update operations via HTTP/HTTPS. The _Management API_ supports JSON payload with hypermedia as well as filtering, sorting and paging. Furthermore the Management API provides permission based access control and standard roles as well as custom role creation.  
+
+The API is protected and needs authentication and authorization based on the security concept.
+
+## API Version
+
+_hawkBit_ provides an consistent Management API interface that guarantees backwards compatibility for future releases by version control.
+
+The current version of the Management API is `version 1 (v1)` with the URI http://localhost:8080/rest/v1/
