+
+## Launcher Scripts
+
+All scripts work from `modules\bot\` directory.
+
+### Windows Command Prompt / PowerShell
+
+```cmd
+set STOCKFISH_PATH=C:\path\to\stockfish.exe
+run_nnue_pipeline.bat
+```
+
+### PowerShell (Colorful, Recommended)
+
+```powershell
+$env:STOCKFISH_PATH = "C:\path\to\stockfish.exe"
+.\run_nnue_pipeline.ps1
+```
+
+### Git Bash / WSL
+
+```bash
+export STOCKFISH_PATH=/c/path/to/stockfish.exe
+bash run_nnue_pipeline.sh
+```
+
+## Python Pipeline Scripts
+
+Located in `modules\bot\python\`:
+
+| Script | Purpose |
+|--------|---------|
+| **generate_positions.py** | Step 1: Generate 500K random positions |
+| **label_positions.py** | Step 2: Evaluate with Stockfish |
+| **train_nnue.py** | Step 3: Train neural network |
+| **export_weights.py** | Step 4: Export to Scala |
+| **run_pipeline.bat** | Windows batch runner |
+| **run_pipeline.sh** | Bash runner |
+
+## Getting Started (3 Steps)
+
+### 1. Install Python
+
+```cmd
+REM Check if Python is installed
+python --version
+
+REM If not, download from https://python.org
+REM During installation, CHECK "Add Python to PATH"
+```
+
+### 2. Install Dependencies
+
+```cmd
+cd modules\bot\python
+pip install -r requirements.txt
+```
+
+### 3. Get Stockfish
+
+- Download from https://stockfishchess.org/download/
+- Extract to `C:\stockfish`
+- Verify: `C:\stockfish\stockfish.exe --version`
+
+### 4. Run Pipeline
+
+```cmd
+cd modules\bot
+set STOCKFISH_PATH=C:\stockfish\stockfish.exe
+run_nnue_pipeline.bat
+```
+
+## FAQ
+
+### How long does it take?
+
+- Step 1 (positions): 2-3 minutes
+- Step 2 (Stockfish): **24-36 hours** ← slowest
+- Step 3 (training): 2-4 hours (faster with GPU)
+- Step 4 (export): 1 minute
+- **Total: 26-40 hours**
+
+### Can I pause and resume?
+
+Yes! The pipeline saves progress:
+1. Press `Ctrl+C` to stop
+2. Run the pipeline again - it will resume where it left off
+
+### Does it use my GPU?
+
+Yes, automatically! If you have NVIDIA GPU:
+- Training will be 5-10x faster
+- Requires CUDA Toolkit (optional, not required)
+
+### Can I test with fewer positions?
+
+Yes! Edit `python\generate_positions.py`:
+```python
+# Change line 9 from:
+for game_num in range(500000):
+
+# To:
+for game_num in range(10000):
+```
+
+This will complete in ~30 minutes instead of 26+ hours.

+
+## Environment Variables
+
+Set these before running the pipeline:
+
+```cmd
+REM Required (unless Stockfish is in PATH)
+set STOCKFISH_PATH=C:\stockfish\stockfish.exe
+
+REM Optional: specify Python version
+set PYTHON_CMD=python3
+```
+
+Or in PowerShell:
+
+```powershell
+$env:STOCKFISH_PATH = "C:\stockfish\stockfish.exe"
+$env:PYTHON_CMD = "python3"
+```
+
+## Troubleshooting Flow
+
+1. **Python not found** → Install from python.org, check "Add to PATH"
+2. **Stockfish not found** → Download from stockfishchess.org, set `STOCKFISH_PATH`
+3. **Module not found** → Run `pip install -r requirements.txt`
+4. **GPU out of memory** → Reduce batch size in `train_nnue.py`
+5. **Pipeline hangs** → Check `training_data.jsonl` size, Stockfish evaluation is slow
+
+See **WINDOWS_SETUP.md** for detailed troubleshooting.
+
+## Next Steps After Pipeline
+
+1. **Verify output:**
+   ```cmd
+   cd ..\..\
+   compile.bat
+   test.bat
+   ```
+
+2. **Use NNUEBot in your engine:**
+   ```scala
+   val bot = new NNUEBot(difficulty, rules, book)
+   val move = bot.nextMove(context)
+   ```
