Drv8825 Installation on gt2560 Rev A +

[Falugafa]

Good morning.
I just bought a Geeetech i3 Pro C that I'm assembling. I also bought 5 drv8825 that I would like to install. On the file I was sent by Geeetech for the assembly I wrote that to install on the board the drv8825 I have to remove two of the three jumper and that the printer only works with one extruder. Is this the procedure I have to follow? Or do I leave the three jumper and replace only the drivers? Will both extruders work?
Thank you
