+
+## Setup Instructions
+
+### 1. Enable GitHub Pages
+
+1. Go to **Settings** → **Pages**
+2. Set **Source** to "GitHub Actions"
+3. Save changes
+
+### 2. Add Repository Secrets (Optional)
+
+For enhanced functionality, add these secrets in **Settings** → **Secrets and variables** → **Actions**:
+
+- `CODECOV_TOKEN`: For code coverage reporting (get from codecov.io)
+- `MAC_CERT`: macOS code signing certificate (for production releases)
+- `MAC_CERT_PASSWORD`: Certificate password
+
+### 3. Configure Dependabot
+
+Edit `.github/dependabot.yml` and replace `your-github-username` with your actual username.
+
+### 4. Branch Protection Rules (Recommended)
+
+Configure in **Settings** → **Branches** → **Branch protection rules**:
+
+For `main` branch:
+- ✅ Require pull request reviews
+- ✅ Require status checks to pass
+  - Select: Python CI, Node.js CI, CodeQL
+- ✅ Require branches to be up to date
+- ✅ Require conversation resolution before merging
+
+### 5. Update README Badges
+
+Copy the status badges from the top of this document to your `README.md` and replace `YOUR-USERNAME`.
+
+## Development Workflow
+
+### Pull Request Workflow
+
+1. **Create feature branch**
+   ```bash
+   git checkout -b feature/my-feature
+   ```
+
+2. **Make changes and commit**
+   ```bash
+   git add .
+   git commit -m "feat: add new feature"
+   ```
+
+3. **Push and create PR**
+   ```bash
+   git push origin feature/my-feature
+   ```
+
+4. **Automated checks run:**
+   - Path filtering determines which workflows run
+   - Linting, type checking, tests execute
+   - Security scans analyze code
+   - Dependency review checks new packages
+
+5. **Review results:**
+   - All checks must pass (green ✓)
+   - Fix any issues reported
+   - Request code review
+
+6. **Merge to main:**
+   - Upon merge, documentation deploys automatically
+   - Main branch remains stable
+
+### Release Workflow
+
+1. **Update version** in `package.json` and `pyproject.toml`
+
+2. **Create and push tag:**
+   ```bash
+   git tag v1.0.0
+   git push origin v1.0.0
+   ```
+
+3. **Automated release:**
+   - Electron builds for all platforms
+   - GitHub Release created automatically
+   - Installers attached to release
+
+## Maintenance
+
+### Updating Workflows
+
+- Workflow files in `.github/workflows/`
+- Use GitHub's workflow editor for syntax validation
+- Test changes in a separate branch first
+
+### Monitoring
+
+- **Actions tab:** View all workflow runs
+- **Security tab:** CodeQL alerts
+- **Pull Requests:** Automated check status
+- **Insights → Dependency graph:** Dependabot PRs
+
+### Troubleshooting
+
+**Tests failing?**
+- Check test logs in Actions tab
+- Run tests locally: `npm test` or `pytest`
+
+**Build failing?**
+- Verify dependencies are installed
+- Check for TypeScript compilation errors
+- Review ESLint/Black formatting
+
+**CodeQL alerts?**
+- Review in Security tab
+- Fix vulnerabilities before merging
+- May require dependency updates
+
+## Performance Optimization
+
+### Caching Strategy
+
+All workflows use dependency caching:
+- **npm:** `~/.npm` cached by Node.js action
+- **pip:** Cached by Python action
+- **Actions:** GitHub Actions cache
+
+### Concurrent Runs
+
+- Multiple PRs can run simultaneously
+- `concurrency` groups prevent duplicate documentation deploys
+- Matrix builds run in parallel
+
+### Cost Management
+
+- Smart path filtering reduces unnecessary runs
+- `continue-on-error` for non-critical checks
+- Artifact retention: 7 days (configurable)
+
+## Best Practices
+
+1. **Keep workflows fast:** Target <10 minutes per workflow
+2. **Use caching:** All dependency installations cached
+3. **Fail fast:** Use `fail-fast: false` in matrices to see all failures
+4. **Security first:** CodeQL and dependency review on all PRs
+5. **Semantic versioning:** Use conventional commits for releases
+6. **Test locally:** Run linters/tests before pushing
+7. **Monitor costs:** GitHub provides 2000 free minutes/month for public repos
