=== Controller ===
=== Controller Dual Module x 2 (2 rotary encoders each PCB) ===
This step is a bit tricky. Depending on your setup it may be useful to solder the 6-pin header row to the back of the PCB, so you can front mount the encoders. In my setup, I bent the 6-pin-row by 90 degrees. The original Zynthian doesn't have this modification, so the pin numbering in the pictures is different!
This step is a bit tricky. Remember that, if you follow the instructions before, you have soldered the pin-rows in the bottom side of PCBs, so numbering is reversed when looking from bottom. You can use a little trick: if you rotate the PCB 180º, then numbering is "left to right" again ;-)
So '''you should look at your controller modules from bottom side and with the pin-row on the top of PCB!'''
'''Looking on the top of the PCB with the 6-pin-row down:'''
'''PHOTO NEEDED HERE!!'''
Some encoders have reversed pin ordering, so you have to change A and B pins.
'''Note:''' Some encoders have reversed pin ordering, so, if you buy the encoders by yourself, perhaps you have to change A and B pins.

'''Warning:''' In this photo the controller modules wiring is reversed (1 by 2, 3 by 4). I will change it ASAP ;-)

=== Writing the image to the SD card ===
If you got the whole image you can write it to an SD-card. Depending on your OS you have to choose how to create the SD-card. You need a minimum size of 16GB, better 32GB for more sample-sets in future. There is a really good manual for this at [https://www.raspberrypi.org/documentation/installation/installing-images/ | https://www.raspberrypi.org/documentation/installation/installing-images/].
If you successfully downloaded the whole image, you can now write it to an SD-card.
You need a minimum size of 16GB, better 32GB SDcard to allow for more instruments and sample-sets in future.
Use Etcher https://etcher.io/ (free software works on Mac, Windows or Linux)
Or do it manually: Depending on your OS you have to choose how to create the SD-card. There is a really good manual for this at [https://www.raspberrypi.org/documentation/installation/installing-images/ | https://www.raspberrypi.org/documentation/installation/installing-images/].
