programming ATXmega256A3BU arduino

Hello,

Im new here, but my friends suggested me to seek for help here since most of you are more knowledgeable.

I have made new microcontroller board using ATXmega256A3BU, its AVR based, so i can assume it can use Arduino to program it.

Any idea how to make my board compatible to be programmed using arduino ?

Any kind of help is apreciated.

Please help me, im so desperate to figure this out.

Thanks
