[App_rpt-users] step by step instructions?

I have Pi 3 & RIM-RC210 and wanting to set up the Pi to hook up to the RC210, Ok, that's easy but I need to find step by step instructions of how to set it up from the start. Programing the PI3 to function an allstar operation. I am some what overwhelmed by which way to go here and where to start... Feeling really stupid right now... I guess age has something to do with it... You know what's really going to P me off is, it's probably real simple and a child of 10 could do it !! Jim N6KMR
