 - Make sure you place the OMDev package into `C:\OMDev\`
   - Follow the instructions in the `C:\OMDev\INSTALL.txt` file
-- You should have an OpenModelica directory you got from OpenModelica GIT repository https://github.com/OpenModelica/OpenModelica
-  - Follow the instructions at the bottom of the page on how to get OpenModelica sources
+- Install Java SE Development Kit (for javac)
+- Install svn tools for windows in TortoiseSVN
+- Install git for windows https://git-scm.com/downloads
+  - do not install git using pacman in msys, it does not work correctly!
+- get OpenModelica from git
+  - start `$OMDEV\tools\msys\mingw64_shell.bat` or `$OMDEV\tools\msys\mingw32_shell.bat` and type:
+
+		```bash
+		cd /path/to/
+		# export the path to your tools: git, svn, java/javac
+		# note: if you have a space in your path to your tool you need to escape it, i.e.: /c/Program\ Files
+		export PATH=$PATH:/c/path/to/git/bin:/c/path/to/svn/tools/bin:/c/path/to/jdk/bin
+		# git clone OpenModelica recursively using the installed git for windows

 - You could use msys2+mingw32 or msys2+mingw64 or Eclipse to build OMC. Follow the instructions in **Compiling OMC using MSYS** or **Compiling OMC using Eclipse**.
