## Usage on Windows 
To build erlsass on Windows 64bit you need to provide GNU gcc and g++ compilers.
Follow the steps below:

1. Download  [MinGW64 for Windows 64bit](http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/mingw-builds/4.9.2/threads-win32/seh/x86_64-4.9.2-release-win32-seh-rt_v3-rev0.7z/download) , and unzip to `C:\mingw64`.

2. Add `C:\mingw64` to your Path environment variable. ( On Windows 10: Open the Start menu, type `environment` in the results click on `Edit environment variables for your account`. Select the `Path` entry and click on `Edit`. )

3. Open CMD or Powershell and execute `gcc --version`. It should show you the gcc version that is present. Do the same for g++. You are now done, please see the section **Install** to continue.
