 See the [device-communication](device-communication) directory for api specifications and implementation.
+
+## Device Management User Interface
+
+See the [device-management-ui](device-management-ui) directory for an example User Interface containing a list
+of tenants with the option to create, update and delete a tenant. Each tenant contains a list of its devices with the
+option to create and delete a device. Furthermore, the credentials of a device can be listed, created and deleted.
+Currently only [Password Credentials](https://www.eclipse.org/hono/docs/concepts/device-identity/#usernamepassword-based-authentication)
+and [RPK Credentials](https://www.eclipse.org/hono/docs/concepts/device-identity/#json-web-token-based-authentication)
+are supported. This UI also contains the functionality to send a configuration or command through the [Device Communication API](device-communication).

+# Device Management UI
+
+This project was generated with [Angular CLI](https://github.com/angular/angular-cli) version 15.2.0. This is an example
+implementation for a Google based deployment in order to give users the possibility to operate with the [Device Registry
+API](https://www.eclipse.org/hono/docs/api/management/) as well as with the [Device Communication API](../device-communication).
+We are recommending using Identity-Aware Proxy ([IAP](https://cloud.google.com/iap/docs)) for your API security. Make
+sure to configure the [OAuth consent](https://developers.google.com/workspace/guides/configure-oauth-consent) screen.
+This UI will provide the possibility to:
+
+1. Access the Device Registry API containing actions like:
+   - listing tenants
+   - creating a new tenant with an ID and messaging-type
+   - deleting a tenant
+   - updating a tenant with another messaging-type
+   - listing devices of a tenant
+   - creating a new device with an ID
+   - deleting a device
+   - listing credentials of a device
+   - creating [Username/Password](https://www.eclipse.org/hono/docs/concepts/device-identity/#usernamepassword-based-authentication) or [JSON Web Token](https://www.eclipse.org/hono/docs/concepts/device-identity/#json-web-token-based-authentication) based credentials
+   - updating JSON Web Token based credentials
+   - deleting credentials
+
+
+2. Access the Device Communication API containing actions like:
+   - listing configs
+   - updating a config
+   - listing states
+   - sending a command
+
+**_NOTE:_** This UI cannot be run without further adjustments! If one wants to use this UI in other environments than on
+Google Cloud, adjustments have to be made
+to **not** include the GoogleService and to update the url suffixes of the services.
+
+### Development server
+
+The development server uses the Proxy Configuration file [proxy.config.json](proxy.config.json). So the target address
+must be updated
+with the address the Hono API is hosted. To run the dev server `ng serve` must be executed. The UI can be then accessed
+via `http://localhost:4200/`.
+The application will automatically reload if any of the source files is changed.
+
+#### Google APIs
+
+If the Device Registry API and/or the Device Communication API is hosted in GCP with Identity Aware Proxy,
+the Google Client ID of the enabled IAP must be provided in the environment
+file [environment.development.ts](../device-management-ui/src/environments/environment.development.ts).
+
+### Build
+
+#### Google APIs
+
+If the UI, the Device Registry API and/or the Device Communication API is hosted in GCP with Identity Aware Proxy,
+the Google Client ID of the enabled IAP must be provided inside an environment variable `ENV_GOOGLE_CLIENT_ID`.
+This environment variable is then set as `googleClientId` inside the environment
+file [environment.ts](../device-management-ui/src/environments/environment.ts).
+
+#### Docker Image
+
+A docker image can be built by executing: `docker build -t {REGISTRY}/{IMAGE_NAME}:{TAG} .`.
+The docker image is installing all the dependencies and building the project with ng build automatically.
+Also, a nginx based image is used for building the server.
+
+### Running unit tests
+
+Run `ng test` to execute the unit tests via [Karma](https://karma-runner.github.io).
