                ### 🔧 How to Set Up Webhooks
                
                1. **Go to Webhook Settings**: Visit [HuggingFace Webhooks](https://huggingface.co/settings/webhooks)
                
                2. **Create New Webhook**: Click "New webhook"
                
                3. **Configure Webhook**:
                   - **URL**: `{your-space-url}/webhooks/tts_automation`
                   - **Secret**: `tts_webhook_secret_2024`
                   - **Events**: Select relevant events (repo updates, discussions, etc.)
                
                4. **Target Repositories**: Add your TTS project repos:
                   - `Toowired/text2speech-gradio-app`
                   - Any model repos you want to monitor
                
                5. **Test**: Use the "Test webhook" button to verify connectivity
                
                ### 📡 Webhook Endpoints Available:
                - `/webhooks/tts_automation` - Main automation endpoint
                - `/webhooks/model_sync` - Model synchronization
                - `/webhooks/usage_tracker` - Usage analytics
                - `/webhooks/error_monitor` - Error notifications
                
                ### 🔐 Security:
                - All webhooks are secured with HMAC signature verification
                - Secret key: `tts_webhook_secret_2024`
                - Only authorized events are processed
