Get openHAB to recognize package = demo after saving /etc/openhab2/services/addons

The demo version was not present in the welcome window even after I deleted the # and replaced “demo” after the =.

I pressed save and cycled Raz power but still was in standard mode.

I understood that any changes that I save in the config files using visual studio are shared with openhab. Please explain and what should i do now?

Got to the demo mode but still do not understand why I cannot initiate a demo from the configuration file.

Paid attention to the link to the demo mode that took me to the documentation. Here is explained the various installations and a link to the demo at .org.

I think this is what I am looking for but still can’t understand why the edited config file did not work.

Please explain.
