Assembly Options
DIY, Semi-Assembled or Fully Assembled?
DIY - Do-it-yourself 
Just the PCB and the components, the rest is up to you. For the die-hard, surface mount and soldering fans. It's not difficult and you can find some great instructions and different methods here. The processor, if there is one included (for the extruder controller and the motherboard), will need to be programmed with a bootloader and your flavour of firmware. To program your chip, you'll need something like an atavrisp mkII; a USBtinyISP or anything along those lines.
Semi-Assembled 
All the hard (read fun) stuff is done by us for you, but you still get to play with your soldering iron and get those last through hole components on there. For the guys that want to use their soldering skills but don't want to worry about the surface mounted stuff. The processor, if there is one included (for the extruder controller and the motherboard), this will need to be programmed with a bootloader and your flavour of firmware. To program your chip, you'll need something like an atavrisp mkII; a USBtinyISP or anything along those lines.
Fully Assembled 
For those that just want plug and play, this is the right option. All components have been soldered to the board and the processor is bootstrapped. Just connect it up and you're A for away. The processor will be included with the latest bootloader, but you're more than welcome to program it yourself if you'd like. They can be reprogrammed quite a few thousand times, so that should give you plenty opportunity to play around with the firmware if you're so inclined.
