FreedomBox and Nextcloud

[marathon]

Hi all. I have installed FreedomBox from stable and on 1st run was sad to 
see that Nextcloud isn't included as an app to install on FreedomBox! Is 
there a how-to that is uptodate and shows how to install and setup on 
FreedomBox or should I uninstall FreedomBox and install Nextcloud as 
standalone app?
Thanks for any and all answers.
