Create and deploy a mobile app in Azure App Service: missing steps

[treadnought]

Following the tutorial "Create and deploy a mobile app in Azure App Service" but about halfway down the page after "This can be created by following a few simple steps:" there are no steps shown.
Also below that after "In the Startup.cs file, replace the content in the namespace region with the following content:" there is no content. There are several more references to sample code that have no code. Very confusing!
