 ## Building
-Building the emulator should be pretty straightforward, just recursively clone the repository and follow the steps:

+> Building requires CMake on all supported platforms
 
 ### Linux
-Building for Linux targets requires SDL2, you may use `apt` on Debian-based distros to obtain it. You will also need a Python interpreter (and `python-is-python3`)
+Building on Linux requires installing SDL3 dependencies and FUSE if you wish to generate AppImages.

-make -j8
+cmake -S . -B build
+cmake --build build -j8
 ```
+Optionally run `cmake --install build` to generate an AppImage.
 
 ### Windows
-Our Windows build system currently targets GCC only, you can get a toolchain through MSYS2 or MinGW. You will additionally need to install a Python interpreter so `build-deps` can execute the gl3w download script.

-Once that's done, just execute the following commands:
+We currently only support GCC as a compiler on Windows, this is because MSVC doesn't have an inline assembler, which we need to embed resources into the executable. This might eventually be fixed though!

 ### macOS
-> [!WARNING]  
-> Iris should support macOS but hasn't been fully tested yet
-
-Building on macOS requires SDL2 and `dylibbundler`, you may install both using `brew` but keep in mind macOS builds aren't actively tested and may not work.
+Iris finally got working macOS builds!
