## 🚀 Deployment

### GitHub Pages Setup Required

**Important**: You need to enable GitHub Pages for the repository:

1. Go to repository Settings → Pages
2. Under "Build and deployment":
   - Source: **GitHub Actions**
3. Save

After this setup, every push to master will:
1. Trigger the docs workflow
2. Build the documentation
3. Deploy to: `https://chandraveshchaudhari.github.io/instantgrade/`

### First Deployment

The documentation will be automatically deployed when you:
1. Enable GitHub Pages (as described above)
2. Push any commit that modifies `docs/` or `src/`
3. Or manually trigger the workflow from GitHub Actions tab

## 📦 Installation for Users

Users can now install with documentation support:

```bash
# Install package only
pip install instantgrade

# Install with documentation building tools
pip install instantgrade[docs]

# Install everything
pip install instantgrade[all]
```

## 🛠️ Building Documentation Locally

Developers can build and preview documentation:

```bash
# Install with doc dependencies
pip install -e ".[docs]"

# Build documentation
cd docs
make html

# View in browser
open build/html/index.html
```

## 📊 What Users Will See

Once deployed, users visiting `https://chandraveshchaudhari.github.io/instantgrade/` will see:

### Homepage Features

## 🔄 Continuous Updates

Documentation will automatically update when:
- Code docstrings are modified
- Documentation markdown files are edited
- New examples are added
- API changes occur

The GitHub Actions workflow ensures documentation is always in sync with the code.

## ✅ Next Steps

1. **Enable GitHub Pages** in repository settings
2. **Update PyPI Trusted Publishing** with new repository name
3. **Create v0.1.0 tag** to trigger first PyPI publish:
   ```bash
   git tag v0.1.0
   git push origin v0.1.0
   ```
4. **Monitor Actions** for successful deployment
5. **Visit documentation** at the GitHub Pages URL
6. **Share the docs link** in README and PyPI description

## 📝 Maintenance

### Adding New Documentation

To add a new page:
1. Create `docs/source/your-page.md`
2. Add it to the toctree in `index.md`
3. Commit and push
4. Docs will auto-deploy

### Updating API Docs

API documentation updates automatically when:
- Docstrings are modified
- New classes/functions are added
- Type hints are updated

No manual intervention needed!

### Version Updates

When releasing new versions:
1. Update `CHANGELOG.md`
2. Update version in `setup.py`
3. Create a git tag
4. Documentation version will update automatically
