Need to reinstall Jail. How to uninstall first.

[Kwekkel]

Hello;

I've installed Alcatraz jail which was working fine. Unfortunately I made a mistake and damaged the installation.
Now I want to reinstall but no go. See below. Obviously I need to remove the old install but it's not clear for me where
and what to remove to uninstall. I've spend quite some time to find answers but could not find it.

I used these instructions for installation:

Thanks.

mkdir /mnt/data/thebrig
chmod a+x /mnt/data/thebrig_install.sh
mnt/data/thebrig_install.sh /mnt/data/thebrig

If you aren't a developer for TheBrig, is a bad idea!
