+To build (and run) the `lua` backend on Windows, a compiled version of the Lua library is required.
+For various reasons (legal, separations of concern, not wanting to ship binary data in the repository),
+you will need to acquire a copy of `lua53.dll` (for example by downloading it from the [luabinaries
+project](http://luabinaries.sourceforge.net/download.html).
+
+To build the `lua` backend for Windows, place `lua53.dll` in a subdirectory `libs/` in the project root
+and run `make lua.dll` inside the `backends/` directory.
+
+At runtime, Windows searches for the file in the same directory as `midimonster.exe`.
