 # Build shadPS4 for Windows
 
-## Download Visual Studio Community 2022
+This tutorial reads as if you have none of the prerequisites already installed. If you do, just ignore the steps regarding installation.
+If you are building to contribute to the project, please omit `--depth 1` from the git invokations.
 
-Download link: [**Visual Studio 2022**](https://visualstudio.microsoft.com/vs/)
+Note: **ARM64 is not supported!** As of writing, it will not build nor run. The instructions with respect to ARM64 are for developers only.
 
-## Requirements
+## Option 1: Visual Studio 2022
 
-### From Visual Studio Community
+### (Prerequisite) Download the Community edition from [**Visual Studio 2022**](https://visualstudio.microsoft.com/vs/)
 
-- Desktop development with C++
+Once you are within the installer:
+1. Select `Desktop development with C++`
+2. Go to "Individual Components" tab
+3. Make sure `C++ Clang Compiler for Windows`, `MSBuild support for LLVM` and `C++ CMake Tools for Windows` are selected
+4. Continue the installation
 
-### From individual components tab install
+### (Prerequisite) Download [**Qt**](https://doc.qt.io/qt-6/get-and-install-qt.html)
 
-- C++ Clang Compiler for Windows (17.0.3)
-- MSBuild support for LLVM (Clang-cl) toolset
+Beware, this requires you to create a Qt account. If you do not want to do this, please follow the MSYS2/MinGW compilation method instead.
 
-- ## Compiling
+1. Select Qt for Visual Studio plugin
+2. Select `msvc2019_64` option or similar. If you are on Windows on ARM / Qualcomm Snapdragon Elite X, select `msvc2019_arm64`
 
-- Open Visual Studio Community and select the **x64-Clang-Release**, **x64-Clang-Debug** or **x64-Clang-RelWithDebInfo**. It should compile just fine.
+Go through the installation normally. If you do not know what components to select, just select the newest Qt version it gives you.
+If you know what you are doing, you may unselect individual components that eat up too much disk space.
+
+Once you are finished, you will have to configure Qt within Visual Studio:
+1. Tools -> Options -> Qt -> Versions
+2. Add a new Qt version and navigate it to the correct folder. Should look like so: `C:\Qt\6.7.1\msvc2019_64` 
+3. Enable the default checkmark on the new version you just created. 
+
+### (Prerequisite) Download [**Git for Windows**](https://git-scm.com/download/win)
+
+Go through the Git for Windows installation as normal
+
+### Compiling with Visual Studio GUI
+
+1. Open Git for Windows, navigate to a place where you want to store the shadPS4 source code folder
+2. Run `git clone --depth 1 --recursive https://github.com/shadps4-emu/shadPS4`
+3. Open up Visual Studio, select `Open a local folder` and select the folder with the shadPS4 source code. The folder should contain `CMakeLists.txt`
+4. Build -> Build All
+
+## Option 2: MSYS2/MinGW
+
+### (Prerequisite) Download [**MSYS2**](https://www.msys2.org/)
+
+Go through the MSYS2 installation as normal
+
+If you are building to distribute, please omit `-DCMAKE_CXX_FLAGS="-O2 -march=native"` within the build configuration step.
+
+Normal x86-based computers, follow:
+1. Open "MSYS2 MINGW64" from your new applications
+2. Run `pacman -Syu`, let it complete;
+3. Run `pacman -S --needed git mingw-w64-x86_64-binutils mingw-w64-x86_64-clang mingw-w64-x86_64-cmake mingw-w64-x86_64-ninja mingw-w64-x86_64-qt6-base`
+4. Run `git clone --depth 1 --recursive https://github.com/shadps4-emu/shadPS4`
+5. Run `cd shadPS4`
+6. Run `cmake -S . -B build -DCMAKE_CXX_COMPILER="clang++.exe" -DCMAKE_C_COMPILER="clang.exe" -DCMAKE_CXX_FLAGS="-O2 -march=native"`
+7. Run `cmake --build build`
+8. To run the finished product, run `./build/shadPS4.exe`
+
+ARM64-based computers, follow:
+1. Open "MSYS2 CLANGARM64" from your new applications
+2. Run `pacman -Syu`, let it complete;
+3. Run `pacman -S --needed git mingw-w64-clang-aarch64-binutils mingw-w64-clang-aarch64-clang mingw-w64-clang-aarch64-cmake mingw-w64-clang-aarch64-ninja mingw-w64-clang-aarch64-qt6-base`
+4. Run `git clone --depth 1 --recursive https://github.com/shadps4-emu/shadPS4`
+5. Run `cd shadPS4`
+6. Run `cmake -S . -B build -DCMAKE_CXX_COMPILER="clang++.exe" -DCMAKE_C_COMPILER="clang.exe" -DCMAKE_CXX_FLAGS="-O2 -march=native"`
+7. Run `cmake --build build`
+8. To run the finished product, run `./build/shadPS4.exe`
+
+## Note on MSYS2 builds
+
+These builds may not be easily copyable to people who do not also have a MSYS2 installation.
+If you want to distribute these builds, you need to copy over the correct DLLs into a distribution folder.
+In order to run them, you must be within the MSYS2 shell environment.
