# - Instant search and filtering
# - Professional responsive interface
# - Real-time workflow statistics
```

### Option 2: Legacy System (Deprecated)
```bash
# ⚠️ WARNING: Generates 71MB file, very slow
python3 generate_documentation.py
# Then open workflow-documentation.html
```

### Import Workflows into n8n
1. Open your [n8n Editor UI](https://docs.n8n.io/hosting/editor-ui/)
2. Click **menu** (☰) → `Import workflow`
3. Choose any `.json` file from the `workflows/` folder

n8n-nodes-base.gmail → Gmail
n8n-nodes-base.slack → Slack
n8n-nodes-base.webhook → Webhook
```

### Purpose Categories
- **Create** - Creating new records/content
- **Update** - Updating existing data
- **Sync** - Synchronizing between systems

## 🏗 Technical Architecture

### Modern Stack (New System)
- **SQLite Database** - FTS5 full-text search, indexed metadata
- **FastAPI Backend** - REST API with automatic documentation
- **Responsive Frontend** - Single-file HTML with embedded assets
- **Smart Analysis** - Automatic workflow categorization

### Key Features
- **Change Detection** - Only reprocess modified workflows
- **Background Indexing** - Non-blocking workflow analysis
- **Compressed Responses** - Gzip middleware for speed

### Database Schema
```sql
-- Optimized for search and filtering
CREATE TABLE workflows (
    id INTEGER PRIMARY KEY,
    filename TEXT UNIQUE,
    name TEXT,
    active BOOLEAN,
    trigger_type TEXT,
    complexity TEXT,
    node_count INTEGER,
    integrations TEXT,  -- JSON array
    tags TEXT,         -- JSON array
    file_hash TEXT     -- For change detection
);

-- Full-text search capability
CREATE VIRTUAL TABLE workflows_fts USING fts5(
    filename, name, description, integrations, tags
);
```

## 🤝 Contributing

### Adding New Workflows
1. **Export workflow** as JSON from n8n
2. **Name descriptively** following the naming convention
3. **Add to workflows/** directory
4. **Test the workflow** before contributing
5. **Remove sensitive data** (credentials, personal URLs)

### Naming Guidelines
- Use clear, descriptive names
- Follow the established format: `[ID]_[Service]_[Purpose].json`
- Maximum 80 characters when possible
- Use underscores instead of spaces

### Quality Standards
- ✅ Workflow must be functional
- ✅ Remove all credentials and sensitive data
- ✅ Add meaningful description in workflow name
- ✅ Test in clean n8n instance
- ✅ Follow naming convention
