Is there a manual for the establishment of Spiceworks?

It should include the follow things:

Windows settings → so that Spiceworks works perfectly

other facilities I have to make

it should be a user manual which is from Spiceworks and where I can follow their steps.

Is there something or do I have to search in the WWW.

There is also a Spiceworks section in the HowTo area aswell that includes some less common tasks and things you can do to extend Spiceworks.
