If should just be a matter of unzipping the download and running /bin/startup.sh. This is documented in the readme, called CONTENTBOX_RUNNING.TXT.
Note, it uses the Java home configured on our OS, so you might need to install Java first before it will run. I think we have a JDK in the download but for some reason don’t actually use it.
Thanks!
