Pardon my ignorance, but having downloaded the WPMU DEV

Hi, Pardon my ignorance, but having downloaded the WPMU DEV Dashboard zip file, I am looking for the 'Usage Instructions' I've been told (by your Beginners' Guide) to consult before uploading the unzipped files to my new WP installation.

Am I missing something or have the Usage Instructions been inadvertantly left out of the package?

Cheers, Gus
