 You should install:
   - [MinGW](http://sourceforge.net/projects/mingw/)'s C compiler
   - [CMake](http://www.cmake.org/cmake/resources/software.html)
+  
+Firstly, you need to change your system's PATH. Navigate to My Computer>System Properties>Advanced System Settings>Environment Variables. 
+
+Then under System Variables, edit your PATH and add C:\MinGW\bin; to the end of it (Change this to your MinGW install directory - C:\MinGW by default). 
+Make sure there's a ";" preceding this entry as well.
 
 Then you should either clone this repo by using git, or just download a [zip of current Master branch](https://github.com/irungentoo/ProjectTox-Core/archive/master.zip) and extract it somewhere.
