Contact Manager Tut: Building the Application Shell: Minor issues

First, take a look at the require elements at the top of the view.

Below the require elements, you can see a pretty standard structure.

There is only one require element, so shouldn't be plural.

The router-view is provided by Aurelia and is a placeholder that indicated where the router should render the current route.

Should be "indicates".

There are a few code boxes that are set to 'JavaScript' and cannot be changed to TypeScript. Easy to workaround, but maybe confusing for beginners.
