+# BreadedSNES
+
+**BreadedSNES** is an up-and-coming cross-platform Super Nintendo (SNES) emulator written in modern C++23. SDL2 is used for audio, video, and input support.
+
+Note, this does not function currently. Maybe it'll boot something in the future. Now is certainly not that time.
+## Build Instructions
+
+### Prerequisites
+
+You will need:
+
+- CMake ≥ 3.16
+- C++23-compatible compiler (GCC, Clang, or MSVC)
+- SDL2 development libraries
+
+---
+
+### Windows
+
+1. Clone the repository and vcpkg:
+
+    ```bash
+    git clone https://github.com/microsoft/vcpkg.git
+    cd vcpkg
+    ./bootstrap-vcpkg.bat
+    ```
+
+2. Install SDL2:
+
+    ```bash
+    ./vcpkg install sdl2
+    ```
+
+3. Build the project:
+
+    ```bash
+    cd path/to/breadedSNES
+    cmake -B build -DCMAKE_TOOLCHAIN_FILE=path/to/vcpkg/scripts/buildsystems/vcpkg.cmake -DCMAKE_BUILD_TYPE=Release
+    cmake --build build --config Release
+    ```
+
+---
+
+###  macOS
+
+1. Install dependencies:
+
+    ```bash
+    brew install cmake sdl2
+    ```
+
+2. Build the project:
+
+    ```bash
+    cmake -B build -DCMAKE_BUILD_TYPE=Release
+    cmake --build build --config Release
+    ```
+

+
+### Packaging
+
+To create distributable packages (e.g. `.zip`, `.dmg`, `.tgz`), run:
+
+```bash
+cd build
+cpack
