Need help installing add on airplanes for FSX.

I am not very fluent with the computers and the unzipping and things like that. I tried reading the read me text and attempted to follow the steps but I just couldn't do it. I recently downloaded the CamSim Boeing 787-8 V2 United NC for windows 10. If somebody could please walk me through it it would be very much appreciated, thank you.

See if this helps.
