-## 🤝 Contributing to OMath or other Orange's Projects
+# Contributing

-### ❕ Prerequisites
+## Prerequisites

- A working up-to-date OMath installation
- C++ knowledge
- Git knowledge
- Ability to ask for help (Feel free to create empty pull-request or PM a maintainer
-  in [Telegram](https://t.me/orange_cpp))
+- C++ compiler with C++23 support (Clang 18+, GCC 14+, MSVC 19.38+)
+- CMake 3.25+
+- Git
+- Familiarity with the codebase (see `INSTALL.md` for setup)

-### ⏬ Setting up OMath
+For questions, create a draft PR or reach out via [Telegram](https://t.me/orange_cpp).

-Please read INSTALL.md file in repository
+## Workflow

-### 🔀 Pull requests and Branches
+1. [Fork](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/working-with-forks/fork-a-repo) the repository.
+2. Create a feature branch from `main`.
+3. Make your changes, ensuring tests pass.
+4. Open a [pull request](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/creating-a-pull-request-from-a-fork) against `main`.

-In order to send code back to the official OMath repository, you must first create a copy of OMath on your github
-account ([fork](https://help.github.com/articles/creating-a-pull-request-from-a-fork/)) and
-then [create a pull request](https://help.github.com/articles/creating-a-pull-request-from-a-fork/) back to OMath.
+## Code Style

-OMath development is performed on multiple branches. Changes are then pull requested into master. By default, changes
-merged into master will not roll out to stable build users unless the `stable` tag is updated.
+Follow the project `.clang-format`. Run `clang-format` before committing.

-### 📜 Code-Style
+## Building

-The orange code-style can be found in `.clang-format`.
+Use one of the CMake presets defined in `CMakePresets.json`:

-### 📦 Building
+```bash
+cmake --preset <preset-name> -DOMATH_BUILD_TESTS=ON
+cmake --build --preset <preset-name>
+```

-OMath has already created the  `cmake-build` and `out` directories where cmake/bin files are located. By default, you
-can build OMath by running `cmake --build cmake-build/build/windows-release --target omath -j 6` in the source
-directory.
+Run `cmake --list-presets` to see available configurations.
+
+## Tests
+
+All new functionality must include unit tests. Run the test binary after building to verify nothing is broken.

 Thanks to everyone who made this possible, including:

 - Saikari aka luadebug for VCPKG port and awesome new initial logo design.
- AmbushedRaccoon for telegram post about omath to boost repository activity.
 - Billy O'Neal aka BillyONeal for fixing compilation issues due to C math library compatibility.
+- Alex2772 for reference of AUI declarative interface design for omath::hud

 And a big hand to everyone else who has contributed over the past!

-OMath is a 100% independent, constexpr template blazingly fast math library that doesn't have legacy C++ code.
+OMath is a 100% independent, constexpr template blazingly fast math/physics/games/mods/cheats development framework that doesn't have legacy C++ code.

 It provides the latest features, is highly customizable, has all for cheat development, DirectX/OpenGL/Vulkan support, premade support for different game engines, much more constexpr stuff than in other libraries and more...

 - **Engine support**: Supports coordinate systems of **Source, Unity, Unreal, Frostbite, IWEngine, CryEngine and canonical OpenGL**.
 - **Cross platform**: Supports Windows, MacOS and Linux.
 - **Algorithms**: Has ability to scan for byte pattern with wildcards in ELF/Mach-O/PE files/modules, binary slices, works even with Wine apps. 
+- **Scripting**: Supports to make scripts in Lua out of box.
+- **Handy**: Allow to design wall hacks in modern jetpack compose like way.

+## <img width="28px" src="https://github.githubassets.com/favicons/favicon.svg" /> Using prebuilt binaries (GitHub Releases)
+
+**Note**: This is the fastest option if you don’t want to build from source.
+
+1. **Go to the Releases page**
+    - Open the project’s GitHub **Releases** page and choose the latest version.
+
+2. **Download the correct asset for your platform**
+    - Pick the archive that matches your OS and architecture (for example: Windows x64 / Linux x64 / macOS arm64).
+
+3. **Extract the archive**
+    - You should end up with something like:
+        - `include/` (headers)
+        - `lib/` or `bin/` (library files / DLLs)
+        - sometimes `cmake/` (CMake package config)
+
+4. **Use it in your project**
+
+   ### Option A: CMake package (recommended if the release includes CMake config files)
+   If the extracted folder contains something like `lib/cmake/omath` or `cmake/omath`, you can point CMake to it:
+
+   ```cmake
+   # Example: set this to the extracted prebuilt folder
+   list(APPEND CMAKE_PREFIX_PATH "path/to/omath-prebuilt")
+
+   find_package(omath CONFIG REQUIRED)
+   target_link_libraries(main PRIVATE omath::omath)
+   ```
+   ### Option B: Manual include + link (works with any layout)
+   If there’s no CMake package config, link it manually:
+   ```cmake
+   target_include_directories(main PRIVATE "path/to/omath-prebuilt/include")
+
+    # Choose ONE depending on what you downloaded:
+    # - Static library: .lib / .a
+    # - Shared library: .dll + .lib import (Windows), .so (Linux), .dylib (macOS)
+    
+    target_link_directories(main PRIVATE "path/to/omath-prebuilt/lib")
