+## Compile and install argon2 library on Windows : 
+
+**IN THEORY : Install [MINGW for Windows](https://sourceforge.net/projects/mingw/files/Installer/) and [Git Bash for Windows](https://git-for-windows.github.io/), open a git bash _as Administrator_ somewhere, and do as follow:**
+
+```
+git clone https://www.github.com/P-H-C/phc-winner-argon2.git argon2-src ;
+cd argon2-src && make && make install;
+```
+
+We wrote IN THEORY cause the Makefile tell to do with MINGW but we cannot test the compilation correctly
+
+## Modify your authme config.yml :
