For the following steps you need Confluence Administrator permissions.
Installing the App
The app is available at the Atlassian Marketplace. To install the add-on, log into your Confluence as a system administrator and navigate to the "Find New Apps" tab of the Universal Plugin Manager (UPM) in the global administration. There you simply search for "SubSpace Navigation for Confluence". You can find the UPM via the menu entry "Find New Apps" or similar. For more details about the UPM please refer to the documentation provided by Atlassian.
Licensing the App
The add-on needs a valid license, otherwise features might not work. Valid licenses are either full licenses, renewal licenses, or 30-day trials and are available at the Atlassian Marketplace. The license model is the same that Atlassian uses for its products – for further information see the Atlassian documentation.
