+# Build Scripts Documentation
+
+ReiLua includes automated build scripts for easy development and release builds.
+
+## Available Scripts
+
+### Development Build Scripts
+- **Windows**: `scripts\build_dev.bat`
+- **Linux/Unix**: `scripts/build_dev.sh`
+
+### Release Build Scripts  
+- **Windows**: `scripts\build_release.bat`
+- **Linux/Unix**: `scripts/build_release.sh`
+
+## Development Build
+
+### Purpose
+Fast iteration during game development with external Lua files and assets.
+
+### Usage
+
+Windows:
+```cmd
+scripts\build_dev.bat
+```
+
+Linux/Unix:
+```bash
+chmod +x scripts/build_dev.sh
+scripts/build_dev.sh
+```
+
+### Features
+- No embedding - loads Lua and assets from file system
+- Fast build times
+- Edit code and assets without rebuilding
+- Automatic cleanup of embedded files
+- Warns if Lua files or assets are in build directory
+- Optional clean build: `scripts\build_dev.bat clean` or `scripts/build_dev.sh clean`
+
+### Output
+- Development executable: `build/ReiLua.exe`
+- Run your game: `cd your_game && path/to/build/ReiLua.exe`
+- Debug mode: `path/to/build/ReiLua.exe --log`
+
+## Release Build
+
+### Purpose
+Create a single-file executable for distribution with all code and assets embedded.
+
+### Preparation
+
+Before running the release build, prepare your files:
+
+```bash
+cd build
+
+# Copy all Lua files
+copy ..\your_game\*.lua .
+# Or: cp ../your_game/*.lua .
+
+# Copy assets
+mkdir assets
+copy ..\your_game\assets\* assets\
+# Or: cp -r ../your_game/assets/* assets/
+```
+
+### Usage
+
+Windows:
+```cmd
+scripts\build_release.bat
+```
+
+Linux/Unix:
+```bash
+chmod +x scripts/build_release.sh
+scripts/build_release.sh
+```
+
+### Features
+- Embeds all Lua files from `build/` directory
+- Embeds all assets from `build/assets/` folder
+- Creates single-file executable
+- Release optimization enabled
+- Verifies Lua files and assets before building
+- Shows summary of embedded files after build
+- Interactive confirmation before building
+
+### Output
+- Release executable: `build/ReiLua.exe`
+- Ready for distribution - no external dependencies
+- Can be renamed to your game name
+
+### Build Configuration
+
+The release build automatically configures:
+- `EMBED_MAIN=ON` - Embeds all Lua files
+- `EMBED_ASSETS=ON` - Embeds all assets (if assets folder exists)
+- `CMAKE_BUILD_TYPE=Release` - Optimized build
+
+## Customizing Your Executable
+
+### Adding Custom Icon
+
+1. Replace `icon.ico` with your own icon file
+2. Keep the same filename or update `resources.rc`
+3. Rebuild
+
+### Changing Executable Properties
+
+Edit `resources.rc` to customize:
+
+```rc
+VALUE "CompanyName", "Your Studio Name"
+VALUE "FileDescription", "Your Game Description"
+VALUE "ProductName", "Your Game Name"
+VALUE "LegalCopyright", "Copyright (C) Your Name, 2025"
+```
+
+### Renaming the Executable
+
+Edit `CMakeLists.txt`:
+```cmake
+project( YourGameName )  # Line 6
+```
+
+After building, the executable will be named `YourGameName.exe`.
+
+## Workflow Examples
+
+### Development Workflow
+
+```bash
+# Initial setup
+scripts\build_dev.bat
+
+# Edit your Lua files in your game directory
+# ... make changes ...
+
+# Just run - no rebuild needed!
+cd your_game
+path\to\build\ReiLua.exe
+
+# If you modify C code, rebuild
+scripts\build_dev.bat
+```
+
+### Release Workflow
+
+```bash
+# 1. Prepare files
+cd build
+copy ..\your_game\*.lua .
+mkdir assets
+copy ..\your_game\assets\* assets\
+
+# 2. Build release
+cd ..
+scripts\build_release.bat
+
+# 3. Test
+cd build
+ReiLua.exe --log
+
+# 4. Distribute
+# Copy build\ReiLua.exe to your distribution folder
+```
+
+## Troubleshooting
+
+### "CMake configuration failed"
+- Ensure CMake is installed and in PATH
+- Ensure MinGW is installed and in PATH
+- Check `CMakeLists.txt` exists in parent directory
+
+### "No Lua files found"
+- Copy your Lua files to `build/` directory before release build
+- Ensure `main.lua` exists (required entry point)
+
+### "Build failed"
+- Check compiler errors in output
+- Ensure all dependencies are installed
+- Try clean build: `scripts\build_dev.bat clean`
+
+### Development build embedding warning
+- The dev build script warns if it finds Lua files or assets in build/
+- These should be removed for development builds
+- The script offers to remove them automatically
+
+## Script Features
+
+### Safety Features
+- Checks for correct directory before running
+- Validates required files exist
+- Warns about potential issues
+- Interactive confirmations for release builds
+- Automatic cleanup of old embedded files
+
+### User Friendly
+- Clear progress messages
+- Colored output (where supported)
+- Helpful error messages
+- Pause at end to review results
+- Quick reference commands shown after build
+
+## Notes
+
+- Development builds are **much faster** than release builds
+- Release builds may take longer due to embedding and optimization
+- Always test your release build before distribution
+- The scripts work on both Windows (CMD/PowerShell) and Unix shells
+- On Unix, make scripts executable: `chmod +x build_*.sh`
