Get 404 Not Found when viewing http://localhost:3001/index.html

[arunk]

Followed the instructions in the README. Had to do a couple of additional things
$ npm install -g nodemon

And change line 7 in caption-service.js from
var $ = require('jQuery');
to
var $ = require('jquery');

But when browsing http://localhost:3001/index.html I get a 404 Not found error.

This is the stacktrace:
