+HawkbitGUI - modern GUI for the Hawkbit Server
+==============================================
+
+This is a GUI for Eclipse Hawkbit [hawkBit](https://github.com/eclipse-hawkbit/hawkbit), an open-source
+backend platform for managing and deploying software and firmware updates to various connected devices.
+This project wants to solve the issue of missing GUI as reported in [#1376](https://github.com/eclipse-hawkbit/hawkbit/issues/1376).
+It is goal to resolve the strong dependencies, and HawkbitGUI does not need at all to be linked with
+Hawkbit's code. It uses the REST API provided by Hawkbit, and it can be installed on any server.
+
+Focus of this project is:
+HawkbitGUI claims  to solve some issues in Hawkbit:
+
+- remove dependencies from the Hawkbit Server.
+  It is a separate project, built outside Hawkbit's Java environment,
+  and it just uses the REST API provided by Hawkbit.
+- GUI and server do not need to run on the same server. GUI can be configured with which server must be connected
+  design easier to change, even if it currently resembles the previous GUI.
+- better UX
