 Since this uses the newer cpp modules, you need to make sure your compiler + build system + IDE supports this. You can
 find more
 info [on this stack overflow post](https://stackoverflow.com/questions/57300495/how-to-use-c20-modules-with-cmake).

+## Toolchain Versions
+#### CMake
+This project requires CMake 3.28 or greater, due to its support for C++ Modules.
+
+#### Compilers
+I have only ever tried to build using the following tools and versions:
+
+- **Ninja**: 1.12.1
+- **Clang**: 18.1.8
+- **C++/GCC**: 14.2.0
+
+If you have issues building on your target platform or compiler, please ensure they can use C++'s `modules` (required by
+the project)
