Any User manual about Microsoft fictional company Contoso ?

Hi Team,

Its very basic question, For explaining different modules in ax and there functioning microsoft has taken an example of fictional company contoso. I just though to search if there is any user manual about contoso group of companies just to understand whats the business and then i will look in ax to map business requirements.

Its very strange there is no document about Contoso. While searching i got one blog where i didnt find much details but very high level documentation.

Is there any source where i can get contoso Distribution and trade related business manaul so that i can map this in ax to understand how business requirements are fulfilled in ax.
