+# AI Coding Agent Instructions
+
+## Project Overview
+This is a 3D printer management web application that provides a real-time interface for monitoring and controlling a Bambu Labs printer via their API. The project uses FastAPI for the backend, HTMX for dynamic UI updates, and Jinja2 for templating.
+
+## Architecture
+
+### Key Components
+- **FastAPI Backend** (`app/main.py`): Handles HTTP endpoints and printer communication
+- **Templates** (`app/templates/`): Jinja2 templates with HTMX for dynamic updates
+- **Static Assets** (`app/static/`): CSS and other static files
+- **Docker Configuration**: Containerized deployment with live code reloading
+
+### Data Flow
+1. FastAPI routes handle HTTP requests
+2. Printer state is managed through `bambulabs_api` library
+3. UI updates via HTMX endpoints returning partial HTML
+
+## Development Environment
+
+### Setup
+```bash
+# Build and start the container
+docker compose up --build
+
+# Development server runs at:
+# - HTTP: http://localhost:8000
+# - MQTT: ports 8883 (TLS), 6000 (unencrypted), 990 (WebSocket TLS)
+```
+
+### Live Development
+- Code changes in `app/` are automatically reloaded
+- Container mounts local `app/` directory for immediate updates
+
+## Key Patterns
+
+### Template Structure
+- Base template: `templates/base.html`
+- Partial templates prefixed with underscore (e.g., `_status.html`, `_connect_area.html`)
+- HTMX used for dynamic content updates
+
+### State Management
+- Connection state tracked in-memory via global variable
+- Printer API interactions wrapped in try/except blocks
+- Status updates polled every 500ms via HTMX trigger
+
+### UI Components
+- Status panel auto-refreshes using `hx-trigger="every 500ms"`
+- Connection state toggles between connect/disconnect UI
+- Error handling displayed in status panel
+
+## Integration Points
+- **Bambu Labs API**: Primary integration via `bambulabs_api` package
+- **MQTT Communication**: Used for real-time printer updates
+- **Configuration File**: Printer connection details stored in `app/config.json`:
+  ```json
+  {
+      "printer": {
+          "ip": "10.0.2.10",
+          "access_code": "e0f815a7",
+          "serial": "00M09A360300272"
+      }
+  }
+  ```
+
+## Common Tasks
+
+### Adding New Printer Data
+1. Add new field to `/status` endpoint in `main.py`
+2. Update status dictionary in the route handler
+3. Add corresponding UI element in `_status.html` template
+
+### Error Handling
+- Wrap printer API calls in try/except blocks
+- Return error status through template context
+- Display errors in UI using dedicated error states
+
+## File Reference
+- `main.py`: Core application logic and routes
+- `templates/_status.html`: Real-time printer status display
+- `templates/index.html`: Main page layout and connection UI
+- `docker-compose.yaml`: Container configuration and port mappings
