 The script downloads Arduino with our modifications and Rambo board support installed, unpacks it into folder PF-build-env-\<version\> on the same level, as your Prusa-Firmware folder is located, builds firmware for MK3 using that Arduino in Prusa-Firmware-build folder on the same level as Prusa-Firmware, runs secondary language support scripts. Firmware with secondary language support is generated in lang subfolder. Use firmware.hex for MK3 variant. Use firmware_\<lang\>.hex for other printers. Don't forget to follow step [2.b](#2b) first for non-MK3 printers.
 ## Windows
+### If you want to use the automated `build.sh` you gonna need to install on you Windows a Linux subsystem or Git-bash
+
+###Steps for Linux subsystem und Windows 10 64-bit:
+- follow the Microsoft guide https://docs.microsoft.com/en-us/windows/wsl/install-win10
+  You can also use the 'prepare_winbuild.ps1' powershell script with Administrator rights
+- Tested versions are at this moment
+  - Ubuntu other may different
+  - After the installation and reboot please open your Ubuntu bash and do following steps
+  - run command `apt-get update`
+  - to install zip run `apt-get install zip`
+  - add few lines at the top of `~/.bashrc` by running `sudo nano ~/.bashrc`
+	
+	export OS="Linux"
+	export JAVA_TOOL_OPTIONS="-Djava.net.preferIPv4Stack=true"
+	export GPG_TTY=$(tty)
+	
+	use `CRTL-X` to close nano and confirm to write the new entries
+  - restart Ubuntu bash
+Now your Ubuntu subsystem is ready to use the automatic `build.sh` script and compile your firmware correctly
+
+####Some Tips for Ubuntu
+- Linux is case sensetive so please don't forget to use capital letters where needed, like changing to a directory
+- To change the path to your Prusa-Firmware location you downloaded and unzipped
+  - Example: You files are under `C:\Users\<your-username>\Downloads\Prusa-Firmware-MK3`
+  - use under Ubuntu the following command `cd /mnt/c/Users/<your-username>/Downloads/Prusa-Firmware-MK3`
+    to change to the right folder
+
+####Compile Prusa-firmware with Ubuntu Linux subsystem installed
+- open Ubuntu bash
+- change to your source code folder (case sensitive)
+- run `./build.sh`
+- follow the instructions
+
+###Steps for Git-bash under Windows 10 64-bit:
+- Download and install the 64bit Git version https://git-scm.com/download/win
+- Also follow these instructions https://gist.github.com/evanwill/0207876c3243bbb6863e65ec5dc3f058
+- Download and install 7z-zip from its official website https://www.7-zip.org/
+  By default, it is installed under the directory /c/Program Files/7-Zip in Windows 10
+- Run `Git-Bash` under Administrator privilege
+- navigate to the directory /c/Program Files/Git/mingw64/bin
+- run `ln -s /c/Program Files/7-Zip/7z.exe zip.exe`
+
+####Compile Prusa-firmware with Git-bash installed
+- open Git-bash
+- change to your source code folder
+- run `bash build.sh`
+- follow the instructions
+
+
 ### 1. Development environment preparation
 
    a. install `"Arduino Software IDE"` for your preferred operating system

+# To excecute this sciprt you gonna need few things on your Windows machine
+#
+# Linux Subsystem Ubuntu
+# 1. Follow these instructions
+# 2. Open Ubuntu bash and get latest updates with 'apt-get upgate'
