+As of v8.0.0 we no longer include jQuery by default. Web development has
+changed a lot since we started this project and while many millions of sites
+still use jQuery there are many sites and applications that don't. 10 years ago
+jQuery _was_ JavaScript for most developers. That's not the case any more so
+we've made the decision to remove jQuery from the project.
+
+If you're interested in including it, you can easily install jQuery using the
+following command:
+
+```
+npm install jQuery
+```
+
+You can then copy the minified file into the `vendor` folder and add jQuery
+to the `index.html` manually.
+
+For reference the last version of the snippet we used to include jQuery looked
+like the following:

+``` html
