## What it is
Kiero is a C++ library that provides a universal graphical hook for games and applications using D3D9-D3D12, OpenGL, or Vulkan, letting developers intercept rendering functions like EndScene or Present. It is no longer maintained, with users directed to the successor project kiero2.

## Use cases
- hook directx rendering functions in a game
- create an overlay for d3d11 games
- intercept vulkan present calls
- build a game mod that draws on screen
- capture or inject code into a game's graphics api

## When to choose
- you need to hook D3D9-D3D12, OpenGL, or Vulkan rendering functions in a Windows game
- you are building an overlay, mod, or rendering interceptor in C++
- you want a small MIT-licensed hooking library you can vendor and maintain yourself

## When to avoid
- you need an actively maintained project - it is officially unmaintained, use kiero2 instead
- you target non-Windows platforms, since it depends on the Windows SDK and DirectX SDK
- you want a high-level overlay framework rather than a low-level function hooking library
