 ## Development Environment:
-Processing 3.5.4
-> Note: Processing 4.0b8 has Bugs, Specifically for Serial API. Highlighted [here in github issues](https://github.com/processing/processing4/issues/490) & [here in forum](https://discourse.processing.org/t/serial-list-on-linux-doesnt-seem-to-work/37075)
+If you want to check the source (for whatever reasons) and play with it, you can use [Processing 3.5.4](https://processing.org/download) on your system.  
+### Notes & credits: 
+1. Uses heavily [controlP5](https://github.com/sojamo/controlp5) Processing library for the GUI. 
+2. As of May 2022, Processing 4.0b8 has a bug Serial API ( related to `Serial.list()` ). Highlighted [here in github issues](https://github.com/processing/processing4/issues/490) & [here in forum](https://discourse.processing.org/t/serial-list-on-linux-doesnt-seem-to-work/37075).
+3. Underneath it uses a tiny [modified version](https://github.com/devATdbsutdio/user_prog) of __MegaTinyCore's__ [serialUPDI based flashing system](https://github.com/SpenceKonde/megaTinyCore/tree/master/megaavr/tools).

+## Prerequisites:
+### Check / Install Python on your system:
+1. __MacOS users__: Although different versions of MacOS comes shipped with differernt versions of python, a quick way to check would be: 
+   - Open your _SPOTLIGHT_ search (`CMD + SPACE`).
+   - Type in `terminal`.
+   - When terminal launches, type in: `python3`. 
+   - If it is not installed, install it by going to this [link](https://www.python.org/downloads/macos/).
+2. __Windows users__: No need to do anything. 
+3. __Linux users__: No need to do anything.
+
+### Install / Update Drivers on your system:
+1. __MacOS users__: MacOS should also come with the serial drivers for the chip we are using, but no harm in upgrading. Install from [here](https://github.com/devATdbsutdio/firmware_updater/blob/main/tools/drivers/CH34XSER_MAC.zip). 
+2. __Windows users__: Windows should also come with the serial drivers for the chip we are using, but no harm in upgrading. Install from [here](https://github.com/devATdbsutdio/firmware_updater/blob/main/tools/drivers/CH34XSER_WIN.zip).
+3. __Linux users__: The built in drivers for CH34x serial chip (that's what we are using in our HW) in Linux Kernel has been broken for a long time. Follow this guide [here](https://gist.github.com/dattasaurabh82/082d13fd61c0d06c7a358c5e605ce4fd).

 ### To Flash PCB test firmware:
 The firmware that should run in the test PCB does things like, on Power ON, it checks various components and reports over serial.
 So we need a Debug serial port (currently which is different than flashing port).
