Openhab2 openhabmin installation

I'm new at openhab2.

Within my installation / website I cannot find the menu point

Extensions/User Interfaces

to install e.g. openhabmin

How can I activate the menu point or what do I have to install?

System: RPi 3, Weezy Path: /usr/share/openhab2

thank you very much in advance and best regards

Andreas

If you have a running openHAB environment, the easiest way is to install additional UIs through the PaperUI.

• Visit http://<openhabIP>:<port> which will bring you to the dashboard.
  • Default Port is 8080 and the IP depends on the way you installed openHAB
• You can then navigate to PaperUI which is the default configuration UI.
• In PaperUi navigate to Add-onsand then chose the USER INTERFACES category
• There you can find all available UIs and install the UI of your choice
• After succesful installation you can access the newly installed ui trough the dashboard

There are other options for the installation of add-ons like uis. You can find an article about this in the docs. https://www.openhab.org/docs/configuration/addons.html
