 not pass in `-Dlua-pc=luajit`, but do pass in `-Dlua-bin=luajit` in the
 Meson command line so that the LuaJIT interpreter can be found correctly.
 
+Additionally, a Makefile for building with Visual Studio is provided at
+`lgi/Makefile.msvc`. This requires GNU Make (i.e. `mingw32-make`), and
+has been tested against the MSVC GTK binary builds provided by the
+[`gvsbuild`](https://github.com/wingtk/gvsbuild) project.

 ## Usage
