+
+This directory is intended for project header files.
+
+A header file is a file containing C declarations and macro definitions
+to be shared between several project source files. You request the use of a
+header file in your project source file (C, C++, etc) located in `src` folder
+by including it, with the C preprocessing directive `#include'.
+
+```src/main.c
+
+#include "header.h"
+
+int main (void)
+{
+ ...
+}
+```
+
+Including a header file produces the same results as copying the header file
+into each source file that needs it. Such copying would be time-consuming
+and error-prone. With a header file, the related declarations appear
+in only one place. If they need to be changed, they can be changed in one
+place, and programs that include the header file will automatically use the
+new version when next recompiled. The header file eliminates the labor of
+finding and changing all the copies as well as the risk that a failure to
+find one copy will result in inconsistencies within a program.
+
+In C, the convention is to give header files names that end with `.h'.
+
+Read more about using header files in official GCC documentation:
+
+* Include Syntax
+* Include Operation
+* Once-Only Headers
+* Computed Includes

+This directory is intended for project specific (private) libraries.
+PlatformIO will compile them to static libraries and link into the executable file.
+
+The source code of each library should be placed in a separate directory
+("lib/your_library_name/[Code]").
+
+For example, see the structure of the following example libraries `Foo` and `Bar`:
+
+|--lib

+|  |  |- Foo.c
+|  |  |- Foo.h
+|  |
+|  |- README --> THIS FILE

-# Python scripts for changing fan speed on MD1200
+# MD1200 fan noise reduction 
 
-This adjusts fan speed "dynamically" based on average backplane temperature reading.
+A set of scripts that automagically set fan speed on a MD1200 (probably MD1220 as well) based on internal temperature readings.
 
 ## PC
 
+### Docker
+
+In .env file change:
+
+```serial_adapter``` which is a serial port you're using. 
+On linux it is /dev/ttyUSBx and on windows it is COMx
+
+```wait_time``` is the interval in which script is checking temperature. By default it is 300 seconds, which is 5 minutes.
+
+Then run with ```sudo docker-compose up -d```
+
+To see output run ```sudo docker container logs MD_Fan_Changer```
+
+### Systemd 
+
+First create virtual enviroment
+
+```
+python3 -m venv venv
+```
+
+Then install required modules
+```
+venv/bin/pip3 install PySerial
+```
+After that you just need to change a few things
+```SERIALADAPTER``` to a port you're using. 
+
+On linux it is /dev/ttyUSBx and on windows it is COMx
+
+```EPPYSLEEPY``` is the interval in which script is checking temperature. By default it is 300 seconds, which is 5 minutes.
+
+### Proxmox LXC
+
+You can also run it in LXC container on your Proxmox host. Just follow the [systemd](###systemd) instructions.
+
+Here you will also need to add ```/dev/ttyUSBx``` to your LXC container. You do it under Resources -> Add -> Device Passthrough -> ```/dev/ttyUSBx``` as Device Path. 
 
 ## STM32F103C6T6
+
+I think it needs a MAX2323 between MD1200.
+
+Will look into that.
