 #### Windows
 
-You will need the GNU build toolchain installed in order for Go to work on Windows. In most cases, this requires installing MinGW-w64.
+You will need the Zig [Zig](https://ziglang.org/) compiler for statically linking CGO.
 
-The easiest way to install this is using MSYS2: https://www.msys2.org/

-If you prefer an alternative method, you can find other methods here: https://www.mingw-w64.org/downloads/
