-# direct3d-headers - updated DirectX headers for Zig
+## Deprecated
 
-This repository provides some updated `include/` and `x86_64/` libraries for Zig/MinGW that enable the use of the latest Direct3D functionality.
+This project has been deprecated and is no longer maintained.
 
-## Headers
-
-We have a small fork of the win32metadata repository which contains the IDL files for Windows SDK:
-
-https://github.com/slimsag/win32metadata
-
-This fork has changes which enable at least the DirectX headers to be compiled with the Wine WIDL compiler. See that repository's commit history for details on what that involves.
-
-Also see this detailed write-up: https://github.com/ziglang/zig/issues/9998#issuecomment-997088467
-
-The files are then copied into this repository:
-
-```sh
-rm -rf include/*
-cp -R win32metadata/generation/WinSDK/RecompiledIdlHeaders/**/d3d*.h include/
-cp -R win32metadata/generation/WinSDK/RecompiledIdlHeaders/**/dx*.h include/
-rm include/dxgi*
-cp win32metadata/generation/WinSDK/RecompiledIdlHeaders/shared/rpcndr.h include/
-```
-
-`rpcndr.h` has a single `#include "rpcndr_hack.h"` line applied which adds a few missing defines.
-
-## Libraries
-
-`x86_64/` contains runtime libraries from the MinGW-w64 project, namely this release:
-
-* https://github.com/niXman/mingw-builds-binaries/releases/tag/13.1.0-rt_v11-rev1
-* `x86_64-13.1.0-release-posix-seh-ucrt-rt_v11-rev1.7z`
-
-```
-cp ~/Downloads/mingw64/x86_64-w64-mingw32/lib/libdxgi.a ./x86_64
-cp ~/Downloads/mingw64/x86_64-w64-mingw32/lib/libdxguid.a ./x86_64
-```
-
-## LICENSE
-
-* `include/` contains files generated from the [microsoft/win32metadata](https://github.com/microsoft/win32metadata/tree/master/generation/WinSDK/RecompiledIdlHeaders) repository, which are [not open source](https://github.com/microsoft/win32metadata/issues/766). The files are fed through Wine's WIDL header generator, which produces new files (arguably we are allowed to MIT license the result, but you may want to presume they are proprietary.)
-* `x86_64/` is licensed under the MinGW-w64-runtime licenses, a copy of which is provided in `COPYING.MinGW-w64-runtime.txt`

-## Issues

-Issues are tracked in the [main Mach repository](https://github.com/hexops/mach/issues?q=is%3Aissue+is%3Aopen+label%3Adirect3d-headers).
