Documentation/Question Affiliates Plugin

Is there any documentation on the Affiliates plugin as there is on the Membership plugin?

I want to know more about the payout options or is it simplistic as I think it may be? I am looking for something that could handle instant payouts to affiliates. I have seen this possible from WP InstantPay, but that plugin is outdated and the changelog is all out of wack from 2010/2011.

Affiliates works fine for me but a client I have is smaller based and I'm trying to avoid much work as possible for her. If this is the extent of Affiliates, are there any new features on checklist to come out. I'm new to the Affiliates but I do understand how it works, but couldn't find any lengthy documentation on it, if any.

Thanks.
