+
+## Files In This Package
+
+| File | Location | Purpose |
+|------|----------|---------|
+| batchtube-launcher.py | backend/ | Windows entry point - starts FastAPI + opens browser |
+| batchtube-windows.spec | backend/ | PyInstaller spec - single-file EXE with all deps |
+| version_info.txt | backend/ | Windows EXE metadata |
+| installer.nsi | project root | NSIS installer script |
+| build_windows.bat | project root | One-click build script |
+
+## Prerequisites
+
+- Python 3.11+ (64-bit) - https://python.org/downloads
+- NSIS 3.x - https://nsis.sourceforge.io/
+- Git - https://git-scm.com
+
+## Quick Build
+
+Double-click build_windows.bat - it handles everything:
+1. Creates virtual environment
+2. Installs all Python dependencies
+3. Downloads yt-dlp.exe
+4. Runs PyInstaller -> backend/dist/BatchTube.exe
+5. Runs NSIS -> BatchTube-Setup-1.0.0.exe
+
+## Manual Build Steps
+
+### Step 1 - Get Source
+
+    scp -r root@212.28.188.26:/root/batchtube-tauri ./batchtube
+    cd batchtube
+
+### Step 2 - Fix config.py DB Path
+
+Edit backend/config.py - replace the DB_PATH line:
+
+    # Before:
+    DB_PATH = os.path.join(os.path.dirname(__file__), "youtube_sipoc.db")
+
+    # After:
+    DB_PATH = os.environ.get(
+        'BATCHTUBE_DB_PATH',
+        os.path.join(os.path.dirname(__file__), "youtube_sipoc.db")
+    )
+
+### Step 3 - Install Dependencies
+
+    cd backend
+    python -m venv venv
+    venv\Scripts\activate
+    pip install -r requirements.txt
+    pip install pyinstaller
+
+### Step 4 - Download yt-dlp
+
+    mkdir ..\tools
+    curl -L https://github.com/yt-dlp/yt-dlp/releases/latest/download/yt-dlp.exe -o ..\tools\yt-dlp.exe
+
+### Step 5 - Build EXE
+
+    pyinstaller batchtube-windows.spec --clean
+    # Output: backend/dist/BatchTube.exe
+
+### Step 6 - Test EXE
+
+    dist\BatchTube.exe
+    # Browser should open to http://127.0.0.1:8765
+
+### Step 7 - Build Installer
+
+    cd ..
+    makensis installer.nsi
+    # Output: BatchTube-Setup-1.0.0.exe
+
+## Troubleshooting
+
+| Problem | Fix |
+|---------|-----|
+| ModuleNotFoundError at runtime | Add to hiddenimports in batchtube-windows.spec |
+| Web UI 404 | Check datas path ('web','backend/web') in spec |
+| DB crash on launch | Apply config.py DB_PATH fix in Step 2 |
+| App closes instantly | Set console=True in spec temporarily to see errors |
+| SmartScreen warning | Code-sign BatchTube.exe with a Windows cert |
+
+## After Install
+
+| Path | Contents |
+|------|----------|
+| C:\Program Files\BatchTube\BatchTube.exe | Application |
+| %APPDATA%\BatchTube\batchtube.db | SQLite database |
+| Start Menu -> BatchTube | Launch shortcut |
+| Desktop | Launch shortcut |
+
+## GitHub Actions - Automated Windows Build
+
+Add to .github/workflows/build.yml:
+
+    build-windows:
+      runs-on: windows-latest
+      steps:
+        - uses: actions/checkout@v4
+        - uses: actions/setup-python@v5
+          with: { python-version: '3.11' }
+        - run: pip install -r backend/requirements.txt pyinstaller
+        - run: cd backend && pyinstaller batchtube-windows.spec --clean
+        - run: choco install nsis -y && makensis installer.nsi
+        - uses: actions/upload-artifact@v4
+          with:
+            name: BatchTube-Windows
+            path: BatchTube-Setup-*.exe
