Question regarding SDL2 / SDL.h

I have been given some code to try out. It enables placing an image on the display at an x, y position. It requires a library.

The codeline to include the library is <SDL2/SDL.h>

Where do I download the appropriate header file? I am running on a Windows 10 box. There should be a list of download options somewhere, and I need to know which line to download. I want to avoid getting into nitty gritty detailed SDL stuff.

You may download both headers and precompiled library with Msys2

Thank you Pompito.
