What problem(s) did you run into that caused you to request additional documentation? What, if any, existing documentation relates to this proposal?
In ug, it just says open index.html with a browser. But if directly open the html file it will render as empty file. See #975 (Note that the path in browser start with File://)
The correct way is open as http://localhost:.../...
What would you like added or modified in the documentation?
Ask user to open the local server first instead of directly open the index.html.
