MARKETPRESS

O.k.-So I'm new here, thanks for sticking with me.
Can someone familiar with Marketpress elaborate on how to configure this plugin to allow others to 'open thier own store' upon my website. I assume I need additional plugins to compliment Marketpress, however I am not to sure what to use. I just need a little personalized 'step-by-step' info from someone who has done "this" ( allow others to open thier own stores ) before.
Thanks for any info.
