## Getting Started

1. **Start all services**: `docker compose up -d`
2. **Check service status**: `docker compose ps`
3. **View logs**: `docker compose logs [service-name]`
4. **Stop services**: `docker compose down`

## Service Dependencies

- **Listmonk** depends on **PostgreSQL** (listmonk-db)
- **NocoDB** depends on **PostgreSQL** (root_db)
- **Static Server** serves content built by **MkDocs**
- **n8n** can integrate with all other services
- All services share the `changemaker` network

## Environment Configuration

Services are configured through environment variables in your `.env` file:

```env
# Port configurations
CODE_SERVER_PORT=8888
LISTMONK_PORT=9000
LISTMONK_DB_PORT=5432
MKDOCS_PORT=4000
MKDOCS_SITE_SERVER_PORT=4001
N8N_PORT=5678

# User and group IDs
USER_ID=1000
GROUP_ID=1000

# Database configuration
POSTGRES_USER=listmonk
POSTGRES_PASSWORD=your_password
POSTGRES_DB=listmonk

# n8n configuration
N8N_ENCRYPTION_KEY=your_encryption_key
N8N_USER_EMAIL=admin@example.com
N8N_USER_PASSWORD=your_password
```

## Monitoring and Maintenance

### Health Checks
```bash
# Check all services
docker compose ps

# Check specific service logs
docker compose logs listmonk-app
docker compose logs code-server
```

### Updates
```bash
# Pull latest images
docker compose pull

# Restart with new images
docker compose down && docker compose up -d
```

### Backups
- **PostgreSQL**: Regular database backups
- **n8n**: Export workflows and credentials
- **Code Server**: Backup configuration and workspace
- **MkDocs**: Version control your documentation

## Troubleshooting

### Common Issues

1. **Port Conflicts**: Ensure ports are not used by other applications
2. **Permission Issues**: Check `USER_ID` and `GROUP_ID` settings
3. **Network Issues**: Verify services can communicate through the `changemaker` network
4. **Data Persistence**: Ensure volumes are properly mounted

### Getting Help

- Check individual service documentation
- Review container logs for error messages
- Verify environment variable configuration
- Test network connectivity between services
