 ## What I am planning to do :
-1. Reverse engineer the schematic of this board (because it is not available) (IN PROGRESS)
-2. Find the best way to flash a custom firmware on the ATMEGA328PU (TO DO)
+1. Reverse engineer the schematic of this board (because it is not available) (DONE !)
+    - The schematic is now available as a pdf file in the **schematic** folder
+2. Find the best way to flash a custom firmware on the ATMEGA328PU (DONE !)
+    - Check the section : **The best way to flash a firmware** section hereunder 
 3. Write a custom firmware for it (TO DO)
+
+## The best way to flash a firmware
+To be honest, the best way to flash our own firmware on this board is to replace the ATMEGA328PU with one which has the Arduino bootloader burnt on it :-(.<br />
+Indeed after looking at the reverse engineered schematic, the SPI pins needed for an ISP are not exposed (they are not even used...).<br />
+Fortunately enough, the onboard FTDI seems to be connected with the DTR line which is connected through a capacitor to the ATMEGA's reset pin that is required by the Arduino bootloader.<br />
+I will test it this weekend and keep you informed.
+
+## But how to repurpose the removed ATMEGA328PU ?
+I will try to restore the chip to a factory state by programming it with a HVPP (High Voltage Parallel Programmer) in order to reset the fuse bytes as well if they are set of course ...<br />
+If I succeed, I'll explain how I did it here.
+
+## FAQ
+1) Why is it not possible to reprogram the chip or to burn a bootloader on the relay board ?
+    - The first issue is that the pins required for an ISP are not exposed :(. The way around it would be to parallel program it, but for that you need to desolder the chip anyway.
+    - The second issue is that the fuse bytes are probably set (I dont actually know for sure) in a way to prevent easy access to the chip. Only a High Voltage Reprogramming of the chip could "unlock it".
