-### Why is the URL for jQuery without `http`?
-
-It is because of the use of [protocol-relative
-URLs](http://paulirish.com/2010/the-protocol-relative-url/).
-
-**N.B.** If you try to view the local web page directly in the browser, the
-browser will fail to load the assets specified using protocol-relative URLs
-as it will attempt to fetch them from the local file system. We recommend you
-use a local HTTP server to test your web pages, or a file hosting service that
-allows you to preview your web pages online (e.g.
-[Dropbox](https://www.dropbox.com/)).
-
-Setting up a local HTTP server can be done using there various
-[one-liners](https://gist.github.com/willurd/5720255):
-
-* PHP 5.4.0+ by running
-  [`php -S localhost:8080`](https://php.net/manual/en/features.commandline.webserver.php)
-  from your local directory
-* Python 2.x by running `python -m SimpleHTTPServer` from your local directory
-* Python 3.x by running `python -m http.server` from your local directory
-* Ruby 1.9.2+ by running `ruby -run -ehttpd . -p8080` from your local directory
-* Node.js by installing and running either
-  [`static -p 8080`](https://www.npmjs.org/package/node-static)
-  or [`http-server -p 8080`](https://www.npmjs.org/package/http-server)

-A list of more complex HTTP servers can be found
