+# RinHash Windows Executables
+
+This directory contains Windows executables for the RinHash algorithm, built using Docker cross-compilation.
+
+## Files
+
+- `rinhash-test.exe` - Simple test executable demonstrating basic functionality
+- `rinhash-windows.exe` - Full RinHash implementation with BLAKE3 + Argon2d + SHA3-256
+
+## Usage
+
+### rinhash-test.exe
+```cmd
+rinhash-test.exe "Hello World"
+```
+
+### rinhash-windows.exe
+```cmd
+rinhash-windows.exe 01000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000
+```
+
+## Technical Details
+
+- **Platform**: Windows x64 (PE32+)
+- **Compiler**: MinGW-w64 cross-compiler
+- **Build Method**: Docker cross-compilation using dockcross/windows-static-x64
+- **Algorithm**: RinHash (BLAKE3 + Argon2d + SHA3-256)
+- **Dependencies**: None (statically linked)
+
+## Build Information
+
+- Built on: Linux host using Docker
+- Cross-compiler: x86_64-w64-mingw32.static-gcc
+- Optimization: -O3 -march=x86-64
+- Linking: Static (-static)
+
+## Testing
+
+Both executables are ready for shipping and testing on Windows systems. They demonstrate:
+
+1. Successful Windows cross-compilation from Linux
+2. RinHash algorithm implementation
+3. Static linking (no external dependencies)
+4. Proper PE32+ executable format
+
+## Notes
+
+- These are demonstration executables showing the RinHash algorithm
+- For production use, integrate with the full cpuminer-opt codebase
+- GPU acceleration would require CUDA/ROCm libraries on Windows
+- Network functionality would require libcurl integration
