What is the current behavior?

If the user investigating ngRx wants to look at the live app to see if it's worthwhile downloading the code he has no way of seeing the functionality without knowing the test user id and password which is buried in the code. The link to the live app should mention the details to avoid those interested having to download the code and plough through it to find the information.

Expected behavior:

Tell me upfront that I can use the app with a userid of "test" and a password of "password"

Minimal reproduction of the problem with instructions:

Version of affected browser(s),operating system(s), npm, node and ngrx:

N/A
