+# Introduction to SDL with MinGW
+
+Without getting deep into the history, MinGW is a long running project that aims to bring gcc to Windows. That said, there's many distributions, versions, and forks floating around. We recommend installing [MSYS2](https://www.msys2.org/), as it's the easiest way to get a modern toolchain with a package manager to help with dependency management. This would allow you to follow the MSYS2 section below. 
+
+Otherwise you'll want to follow the "Other Distributions" section below.
+
+We'll start by creating a simple project to build and run [hello.c](hello.c).
+
+# MSYS2
+
+Open the `MSYS2 UCRT64` prompt and then ensure you've installed the following packages. This will get you working toolchain, CMake, Ninja, and of course SDL3.
+
+```sh
+pacman -S mingw-w64-ucrt-x86_64-gcc mingw-w64-ucrt-x86_64-ninja mingw-w64-ucrt-x86_64-cmake mingw-w64-ucrt-x86_64-sdl3
+```
+
+## Create the file CMakeLists.txt
+```cmake
+cmake_minimum_required(VERSION 3.26)
+project(hello C CXX)
+
+find_package(SDL3 REQUIRED)
+
+add_executable(hello)
+
+target_sources(hello
+PRIVATE
+    hello.c
+)
+
+target_link_libraries(hello SDL3::SDL3)
+```
+
+## Configure and Build:
+```sh
+cmake -S . -B build
+cmake --build build
+```
+
+## Run:
+
+The executable is in the `build` directory:
+```sh
+cd build
+./hello
+```
+
+# Other Distributions
+
+Things can get quite complicated with other distributions of MinGW. If you can't follow [the cmake intro](INTRO-cmake.md), perhaps due to issues getting cmake to understand your toolchain, this section should work.
+
+## Acquire SDL
+
+Download the `SDL3-devel-<version>-mingw.zip` asset from [the latest release.](https://github.com/libsdl-org/SDL/releases/latest) Then extract it inside your project folder such that the output of `ls SDL3-<version>` looks like `INSTALL.md  LICENSE.txt  Makefile  README.md  cmake  i686-w64-mingw32  x86_64-w64-mingw32`.
+
+## Know your Target Architecture
+
+It is not uncommon for folks to not realize their distribution is targeting 32bit Windows despite things like the name of the toolchain, or the fact that they're running on a 64bit system. We'll ensure we know up front what we need:
+
+Create a file named `arch.c` with the following contents:
+```c
+#include <stddef.h>
+#include <stdio.h>
+int main() {
+    #if defined(__x86_64__) || defined(_M_X64) || defined(i386) || defined(__i386__) || defined(__i386) || defined(_M_IX86)
+        size_t ptr_size = sizeof(int*);
+        if (4 == ptr_size) puts("i686-w64-mingw32");
+        else if (8 == ptr_size) puts("x86_64-w64-mingw32");
+        else puts("Unknown Architecture");
+    #else
+        puts("Unknown Architecture");
+    #endif
+    return 0;
+}
+```
+
+Then run
+
+```sh
+gcc arch.c
+./a.exe
+```
+
+This should print out which library directory we'll need to use when compiling, keep this value in mind, you'll need to use it when compiling in the next section as `<arch>`. If you get "Unknown Architecture" please [report a bug](https://github.com/libsdl-org/SDL/issues).
+
+
+## Build and Run
+
+Now we should have everything needed to compile and run our program. You'll need to ensure to replace `<version>` with the version of the release of SDL3 you downloaded, as well as use the `<arch>` we learned in the previous section.
+
+```sh
+gcc hello.c -o hello.exe -I SDL3-<version>/<arch>/include -L SDL3-<version>/<arch>/lib -lSDL3 -mwindows 
+cp SDL3-<version>/<arch>/bin/SDL3.dll SDL3.dll
+./hello.exe
+```
