-How to run slidewiki application?
I followed your documentation but it's coming blank page.
The microservice uri is getting error.
if i use https://signalingservice.experimental.slidewiki.org/socket.io/socket.io.js , application is not working.
if i use slidewiki live socket.io URL(https://signalingservice.slidewiki.org/socket.io/socket.io.js), that time application is coming blank.
I attached screenshot.
