 ## [Unreleased]
 ### Added
-- Support for Windows 64-bit.
+- Support for Windows 64-bit and compiling on Windows using MSVC.
 
 ### Changed
 - Updated build script. `./build.sh` will create a debug build of the gdnative library for the current platform. `./build.sh release-all` will create release build of the gdnative library for every supported platform.

 #### Other Linux Distributions
 Will probably be similar to the above. When in doubt check the documentation in the submodule repos, the [build.sh] script, and the [SConstruct] file.
 
+### Windows
+Compiling on Windows for 64-bit is supported using [Visual Studio Community](https://visualstudio.microsoft.com/vs/community/) version 2019, although other versions might work. See the [Godot documentation](https://docs.godotengine.org/en/stable/development/compiling/compiling_for_windows.html) for more information on setting up the development environment.
+See the [github workflow file](.github/workflows/main.yml) for the commands that can be used to build the native libraries.

 ### Other Operating Systems
-This plugin is not currently supported for other operating systems (e.g. MacOS, Windows). If you manage to build it on one of these platforms, please submit a PR for this readme.
