Configure has some general configuration options:
Hostname
Hostname is the local name by which other devices on the local network can reach your FreedomBox. Default is freedombox.
Domain Name
Domain name is the global name by which other devices on the Internet can reach your FreedomBox. The value set here is used by the Chat Server (XMPP), Certificates (Let's Encrypt), and Monkeysphere.
Default App
This is an advanced option that allows you to set something other than FreedomBox Service (Plinth) as the default application to be served on the domain name of the FreedomBox. For example, if your FreedomBox's domain name is https://myfreedombox.rocks and you set MediaWiki as the default app, visiting https://myfreedombox.rocks will take you to https://myfreedombox.rocks/mediawiki/ instead of the usual https://myfreedombox.rocks/plinth/. Only web applications served from FreedomBox are allowed as choices.
Warning: Once some other app is set as the default app, you can only navigate to the FreedomBox Service (Plinth) by typing https://myfreedombox.rocks/plinth/ into the browser. /freedombox can also be used as an alias to /plinth
Tip: Bookmark the URL of FreedomBox Service (Plinth) before changing the default app to some other app.
