 Hi there
 
 This is a very simplistic little game engine, mainly trying to wrap around vulkan and the operating system's windowing, input and audio system.
-This is using the last programming language you will ever need, [Nim](https://nim-lang.org/)
+I am using the last programming language you will ever need, [Nim](https://nim-lang.org/)
 
 Building
 --------
 
-Run ```nim help``` to see a list of available build commands.
-
-It is required to download the glslangValidator binary into the ```examples/``` directory in order to be able to build.
-There is a nim command for this that works on linux.
-
-Compilation on Windows
-----------------------
+Requires Nim to be installed and ```glslangValidator``` to be downloaded to the
+directory of the main compilation file (e.g. into ```examples/``` in order to
+compile the examples). It can be downloaded at
+https://github.com/KhronosGroup/glslang/releases/.
 
-Requires a Windows SDK to be installed (e.g. via Visual Studio Build Tools).
-Also, using Nim on Windows with mingw seems to be way faster than with vcc/lc.
-For compilation with vcc/ls, install additionaly (with Visual Studio Build Tools):
-- Windows Universal C Runtime (some important files)
-- Windows CRT SDK (some important header files)
-- Some version of MSVC (the compiler)
-
-glslangValidator cannot yet be downloaded automatically on windows, check config.nim for instructions.
+Run ```nim help``` to see a list of available build commands.
 
 Roadmap
 -------
 
-Still tons to do, but it feels like the worst things (except audio maybe?) are over the hill.
+Still tons to do. Making render pipeline and scenegraph somewhat compatible
+seems like it will require quite a bit more of work. Also, audio might require
+quite a bit of work, no experience there.
