+# vcpkg Integration for Windows Builds
+
+This document describes how to use vcpkg for Windows builds in Visual Studio with YAZE.
+
+## Overview
+
+vcpkg is Microsoft's C++ package manager that simplifies dependency management for Windows builds. YAZE now includes full vcpkg integration with manifest mode support for automatic dependency resolution.
+
+## Features
+
+- **Manifest Mode**: Dependencies are automatically managed via `vcpkg.json`
+- **Visual Studio Integration**: Seamless integration with Visual Studio 2019+
+- **CMake Presets**: Pre-configured build presets for Windows
+- **Automatic Setup**: Setup scripts for easy vcpkg installation
+
+## Quick Start
+
+### 1. Setup vcpkg
+
+Run the automated setup script:
+```cmd
+# Command Prompt
+scripts\setup-vcpkg-windows.bat
+
+# PowerShell
+.\scripts\setup-vcpkg-windows.ps1
+```
+
+### 2. Build with vcpkg
+
+Use the Windows presets in CMakePresets.json:
+
+```cmd
+# Debug build
+cmake --preset windows-debug
+cmake --build build --preset windows-debug
+
+# Release build
+cmake --preset windows-release
+cmake --build build --preset windows-release
+```
+
+## Configuration Details
+
+### vcpkg.json Manifest
+
+The `vcpkg.json` file defines all dependencies:
+
+```json
+{
+  "name": "yaze",
+  "version": "0.3.1",
+  "dependencies": [
+    "zlib",
+    "libpng", 
+    "sdl2",
+    "abseil",
+    "gtest"
+  ]
+}
+```
+
+### CMake Configuration
+
+vcpkg integration is handled in several files:
+
+- **CMakeLists.txt**: Automatic toolchain detection
+- **cmake/vcpkg.cmake**: vcpkg-specific settings
+- **CMakePresets.json**: Windows build presets
+
+### Build Presets
+
+Available Windows presets:
+
+- `windows-debug`: Debug build with vcpkg
+- `windows-release`: Release build with vcpkg
+
+## Dependencies
+
+vcpkg automatically installs these dependencies:
+
+- **zlib**: Compression library
+- **libpng**: PNG image support
+- **sdl2**: Graphics and input handling
+- **abseil**: Google's C++ common libraries
+- **gtest**: Google Test framework (with gmock)
+
+## Environment Variables
+
+Set `VCPKG_ROOT` to point to your vcpkg installation:
+
+```cmd
+set VCPKG_ROOT=C:\path\to\vcpkg
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **vcpkg not found**: Ensure `VCPKG_ROOT` is set or vcpkg is in the project directory
+2. **Dependencies not installing**: Check internet connection and vcpkg bootstrap
+3. **Visual Studio integration**: Run `vcpkg integrate install` from vcpkg directory
+
+### Manual Setup
+
+If automated setup fails:
+
+```cmd
+git clone https://github.com/Microsoft/vcpkg.git
+cd vcpkg
+.\bootstrap-vcpkg.bat
+.\vcpkg.exe integrate install
+```
+
+## Benefits
+
+- **Consistent Dependencies**: Same versions across development environments
+- **Easy Updates**: Update dependencies via vcpkg.json
+- **CI/CD Friendly**: Reproducible builds
+- **Visual Studio Integration**: Native IntelliSense support
+- **No Manual Downloads**: Automatic dependency resolution
+
+## Advanced Usage
+
+### Custom Triplets
+
+Override the default x64-windows triplet:
+
+```cmd
+cmake --preset windows-debug -DVCPKG_TARGET_TRIPLET=x86-windows
+```
+
+### Static Linking
+
+For static builds, modify `cmake/vcpkg.cmake`:
+
+```cmake
+set(VCPKG_LIBRARY_LINKAGE static)
+set(VCPKG_CRT_LINKAGE static)
+```
