-#### jQuery CDN for jQuery
-
-The jQuery CDN version of the jQuery JavaScript library is referenced towards
-the bottom of the page. A local fallback of jQuery is included for rare
-instances when the CDN version might not be available, and to facilitate offline
-development.
-
-The jQuery CDN version was chosen over other potential candidates ([like
-Google's Hosted Libraries](https://developers.google.com/speed/libraries/))
-because it's fast ([comparable or faster than Google by some
-measures](https://www.cdnperf.com/#jsdelivr,cdnjs,google,yandex,microsoft,jquery,bootstrapcdn/https/90))
-and, (unlike Google's CDN) is available to China's hundreds of millions of
-internet users. For many years we
-[chose](https://github.com/h5bp/html5-boilerplate/issues/1191) the Google Hosted
-version over the jQuery CDN because it was available over HTTPS (the jQuery CDN
-was not,) and it offered a better chance of hitting the cache lottery owing to
-the popularity of the Google CDN. The first issue is no longer valid and the
-second is far outweighed by being able to serve jQuery to users in China.
-
-While the jQuery CDN is a strong default solution your site or application may
-require a different configuration. Testing your site with services like
-[WebPageTest](https://www.webpagetest.org/) and browser tools like [PageSpeed
-Insights](https://developers.google.com/speed/pagespeed/insights/) will help you
-examine the real world performance of your site and can show where you can
-optimize your specific site or application.
