 ## Compiling
 
 Dependencies:
- * You need to have the [Godot headers](https://github.com/GodotNativeTools/godot_headers) saved somewhere on your system
+
+ * You need [Godot headers](https://github.com/GodotNativeTools/godot_headers), this is now a submodule of this repo
  * clang or any decent C compiler that's C11 or C99 compatible
 
 ### Scons (cross platform)
 You can use scons to compile the library if you have it installed:
 
-    scons platform=PLATFORM
+```
+scons platform=PLATFORM
+```
 
 Where platform is: x11, osx or windows
-Optionally you can specify:
-
-    headers=/PATH/TO/GODOT/HEADERS
 
 ### Linux
 To compile the library on Linux, do
 
-    cd src
+```
-    clang -std=c11 -fPIC -c -I/PATH/TO/GODOT/HEADERS simple.c -o simple.os
+cd src
-    clang -shared simple.os -o ../bin/libsimple.so
+clang -std=c11 -fPIC -c -I../godot_headers simple.c -o simple.os
+clang -shared simple.os -o ../demo/bin/x11/libsimple.so
+```
 
-This creates the file `libsimple.so` in your `src` directory.
+This creates the file `libsimple.so` in your `demo/bin/x11` directory.
 For windows you need to find out what compiler flags need to be used, I don't know which ones. (If you do, feel free to fork and update this project and README)
 
 ### Mac OS X
 On Mac OS X:
 
-    cd src
+```
-    clang -std=c11 -fPIC -c -I/PATH/TO/GODOT/HEADERS simple.c -o simple.os -arch i386 -arch x86_64
+cd src
-    clang -dynamiclib simple.os -o ../bin/libsimple.dylib -arch i386 -arch x86_64
+clang -std=c11 -fPIC -c -I../godot_headers simple.c -o simple.os -arch i386 -arch x86_64
+clang -dynamiclib simple.os -o ../demo/bin/osx/libsimple.dylib -arch i386 -arch x86_64
+```
 
 This creates the file 'libsimple.dylib' as a universal binary (or alternatively remove one of the -arch options from both commands if you want to just compile for one architecture).
 
 ### Windows
-To be added
+On Windows:
+
+```
+cd src
+cl /Fosimple.obj /c simple.c /nologo -EHsc -DNDEBUG /MD /I. /I../godot_headers
+link /nologo /dll /out:..\demo\bin\win64\libsimple.dll /implib:..\demo\bin\win64\libsimple.lib simple.obj
+```
+
+This creates the file `libsimple.dll` in your `demo/bin/win64` directory.
