+* Using the included batch files.

 For your convenience a `build.bat` file is included in each demo. These will use Visual Studio's command-line tools to

-#### Within Visual Studio
+### Within Visual Studio
 
 Create a new _Empty_, _C++_, _Console_ project.
 You can then easily install the required libraries with _NuGet_, under the _Project_ menu of a new C++ project, and you're ready to draw a triangle in 5 minutes.

 1. In the _Browse_ tab search for and install; `glfw`, and `glew`. For later tutorials you can also find `assimp`, and `freetype`, when required.
 2. You need to add the text `opengl32.lib` to your linker input string. You can find this in _Project->Properties->Configuration Properties->Linker->Input->Additional Dependencies_. Just add `opengl32.lib;` to the front of the long string of dependencies so that it changes to `opengl32.lib;kernel32.lib;user32;...`.
 3. You do not need to add the libraries you installed _via_ NuGet to the linker string.
 4. You can now compile a _Hello Triangle_ demo for OpenGL using GLFW and GLEW.

 If you would rather do things the old fashioned way, without using a package manager, I have recorded a 2020 video stream tutorial where I show how to get Visual Studio set up and start programming OpenGL, including downloading and setting up libraries.

 This includes a very verbose set-up of Visual Studio 2019 with helper libraries.

-### Windows with GCC
+## Compiling on Windows with GCC
 
 * Install the GNU Compiler Collection - usually by installing MinGW. I suggest the minimal MinGW GCC distribution at [https://nuwen.net/mingw.html](https://nuwen.net/mingw.html).
 * Open a console and `cd` to the demo of choice.
