Make the following clear:

• If you perform the Getting Started, you are using the IDM showcase app as an example
• If you wanna run the showcase apps with all services, you must navigate to Showcase Apps in navigation tree
• If you're navigating the service specific documentation, the assumption is that you are adding that service to an existing app or a blank app

Need to change:

• intro to getting started
• prereqs in each service doc
• intro to showcase apps section
