[ic] How do I do authorize.net setup for 4.6.5

[Robert Trembath]

I been using interchange in a development environment for about 6 months and am finally 
ready to put it into production use. I've read thru the docs some but
can't seem to find a simple outline of how to setup payment by CC thru
authorize.net. I have my account with them now open but need a little
direction. 

Any help from anyone with experience with this would be appreciated.

Thanks,
Robert
