Your in for a world of pain 
This page helped me a lot - pydPiper Addon
Best advice I can give is once it starts installing walk away for an hour, sometimes it doesn’t appear to complete, but once cpu activity dropped to 1% on mine I manually closed the ssh connection and activated the addons in the addon section of the web gui
You will probably need to tweak the pages config file to get exactly what you want displayed
Also if you do a search there’s some recent posts on the subject (some are mine)
Good luck
