 ### windows
-If you're on windows, you have my condolences.
+Building on Windows is a bit more involved. It's the same process, though you will need a bit
+more software:
+
+* Install mingw-w64 from [mingw-builds](http://mingw-w64.org/doku.php/download/mingw-builds)
+	* Version: `latest` (e.g. `7.3.0`);
+	* Architecture: `x86_64`;
+	* Threads: `win32`;
+	* Exceptions: `seh`;
+	* Build Revision: `latest`;
+	* Destination folder: any folder your user owns, e.g. `C:/Users/yourname/documents`
+* Install SDL2, SDL2_img, and SDL2_ttf from here: [sdl2](http://libsdl.org/download-2.0.php), [sdl2_image](https://www.libsdl.org/projects/SDL_image), [sdl2_ttf](https://www.libsdl.org/projects/SDL_ttf)
+	* Extract these zip files;
+	* Copy the `x86_64-w64-mingw32` into your mingw folder specified when installing mingw-w64.
+* Add the `mingw` bin folder to the `PATH`
+
+Once this is complete, open up a terminal and type the following:
+
+```bash
+$ go get github.com/felixangell/phi
+$ cd $GOPATH/src/github.com/felixangell/phi
+$ go build
+$ ./phi
+```
+
+Note that you should run `go install` so that the dependencies aren't being rebuilt for faster compile times.
 
 ## configuration
 Configuration files are stored in `$HOME/.phi-editor/config.toml`. Note that
