'Best Practices' for inviting prospective investors to a Box VDR (virtual data room)?

We've nearly completed uploading all of our Company's due diligence content into a series of folders.  What's the best way to manage the invitation and access of the many reviewers of this content?  Do we create separate folders/groups for each party?  Is there a good Box Support 'how-to' link for this?  Any/all help is greatly appreciated!
