+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing

-A system that allows Monitoring of Raspberry PI('s) and it's running Minecraft Server(s) on PC and Mac
+A system that allows Monitoring of Raspberry PI('s) PC and Mac as well as controlling their cooling fans.
+
+## Why?
+The idea was to create software to allow the different components inside my diy Raspberry PI server rack to communicate which each other. This is done with serial connections as they are very easy to set up and use.
+
+## Description
+Each module has it's own `README.md` file.

+# Arduino module
+
+## task
+The Arduino module manages the overall assets of the server rack. Those are the LCD display, the button panel and the internal and external serial communication between the computer, Raspberry PI4,  Raspberry PI1.2 and itself. It also collects data about the system such as package loss, etc...
+
+## Build from source
+1. The following packages/programs need to be installed and setup:
+
+    - arduino-cli with the following libraries installed (or use libs provided in `libs/`):
+        - SoftwareSerial
+        - LiquidCristal
+    - git (or clone repository manually) 
+
+2. open a terminal and run the following commands:
+
+```
+git clone https://github.com/J-onasJones/PI-server-rack.git
+cd PI-server-rack
+arduino-cli --fqbn [arduino board of your choice] arduino
+```
+3. to upload the sketch to an arduino run the following command:
+```
+arduino-cli upload --fqbn [arduino board of your choice] -p [arduino port name] arduino
+```
+As an example on Linux for the `Arduino Nano` the following:
+```
+arduino-cli upload --fqbn arduino:avr:nano -p /dev/ttyUSB0 arduino
+```
