+# MyDocManager
+
+## Overview
+
+MyDocManager is a real-time document processing application that automatically detects files in a monitored directory, processes them asynchronously, and stores the results in a database. The application uses a modern microservices architecture with Redis for task queuing and MongoDB for data persistence.
+
+## Architecture
+
+### Technology Stack
+- **Backend API**: FastAPI (Python 3.12)
+- **Task Processing**: Celery with Redis broker
+- **Document Processing**: EasyOCR, PyMuPDF, python-docx, pdfplumber
+- **Database**: MongoDB
+- **Frontend**: React
+- **Containerization**: Docker & Docker Compose
+- **File Monitoring**: Python watchdog library
+
+### Services Architecture
+    ┌─────────────────┐    ┌─────────────┐    ┌─────────────┐    ┌─────────────┐    ┌─────────────┐
+    │   Frontend      │    │ file-       │    │    Redis    │    │   Worker    │    │  MongoDB    │

+    └─────────────────┘    └─────────────┘    └─────────────┘    └─────────────┘    └─────────────┘
+
+### Docker Services
+1. **file-processor**: FastAPI + real-time file monitoring + Celery task dispatch
+2. **worker**: Celery workers for document processing (OCR, text extraction)
+3. **redis**: Message broker for Celery tasks
+4. **mongodb**: Final database for processing results
+5. **frontend**: React interface for monitoring and file access
+
+## Data Flow
+
+1. **File Detection**: Watchdog monitors target directory in real-time
+2. **Task Creation**: FastAPI creates Celery task for each detected file
+3. **Task Processing**: Worker processes document (OCR, text extraction)
+4. **Result Storage**: Processed data stored in MongoDB
+5. **Monitoring**: React frontend displays processing status and results
+
+## Document Processing Capabilities
+
+### Supported File Types
+- **PDF**: Direct text extraction + OCR for scanned documents
+- **Word Documents**: .docx text extraction
+- **Images**: OCR text recognition (JPG, PNG, etc.)
+
+### Processing Libraries
+- **EasyOCR**: Modern OCR engine (80+ languages, deep learning-based)
+- **PyMuPDF**: PDF text extraction and manipulation
+- **python-docx**: Word document processing
+- **pdfplumber**: Advanced PDF text extraction
+
+## Development Environment
+
+### Container-Based Development
+The application is designed for container-based development with hot-reload capabilities:
+- Source code mounted as volumes for real-time updates
+- All services orchestrated via Docker Compose
+- Development and production parity
+
+### Key Features
+- **Real-time Processing**: Immediate file detection and processing
+- **Horizontal Scaling**: Multiple workers can be added easily
+- **Fault Tolerance**: Celery provides automatic retry mechanisms
+- **Monitoring**: Built-in task status tracking
+- **Hot Reload**: Development changes reflected instantly in containers
+
+### Docker Services
+1. **file-processor**: FastAPI + real-time file monitoring + Celery task dispatch
+2. **worker**: Celery workers for document processing (OCR, text extraction)
+3. **redis**: Message broker for Celery tasks
+4. **mongodb**: Final database for processing results
+5. **frontend**: React interface for monitoring and file access

+
+## Docker Commands Reference
+
+### Initial Setup & Build
+
+```bash
+# Build and start all services (first time)
+docker-compose up --build
+
+# Build and start in background
+docker-compose up --build -d
+
+# Build specific service
+docker-compose build file-processor
+docker-compose build worker
+```
+
+### Development Workflow
+
+```bash
+# Start all services
+docker-compose up
+
+# Start in background (detached mode)
+docker-compose up -d
+
+# Stop all services
+docker-compose down
+
+# Stop and remove volumes (⚠️ deletes MongoDB data)
+docker-compose down -v
+
+# Restart specific service
+docker-compose restart file-processor
+docker-compose restart worker
+docker-compose restart redis
+docker-compose restart mongodb
+```
+
+### Monitoring & Debugging
+
+```bash
+# View logs of all services
+docker-compose logs
+
+# View logs of specific service
+docker-compose logs file-processor
+docker-compose logs worker
+docker-compose logs redis
+docker-compose logs mongodb
+
+# Follow logs in real-time
+docker-compose logs -f
+docker-compose logs -f worker
+
+# View running containers
+docker-compose ps
+
+# Execute command in running container
+docker-compose exec file-processor bash
+docker-compose exec worker bash
+docker-compose exec mongodb mongosh
+```
+
+### Service Management
+
+```bash
+# Start only specific services
+docker-compose up redis mongodb file-processor
+
+# Stop specific service
+docker-compose stop worker
+docker-compose stop file-processor
+
+# Remove stopped containers
+docker-compose rm
+
+# Scale workers (multiple instances)
+docker-compose up --scale worker=3
+```
+
+### Hot-Reload Configuration
+
+- **file-processor**: Hot-reload enabled via `--reload` flag
+  - Code changes in `src/file-processor/app/` automatically restart FastAPI
+- **worker**: No hot-reload (manual restart required for stability)
+  - Code changes in `src/worker/tasks/` require: `docker-compose restart worker`
+
+### Useful Service URLs
+
+- **FastAPI API**: http://localhost:8000
+- **FastAPI Docs**: http://localhost:8000/docs
+- **Health Check**: http://localhost:8000/health
+- **Redis**: localhost:6379
+- **MongoDB**: localhost:27017
+
+### Testing Commands
+
+```bash
+# Test FastAPI health
+curl http://localhost:8000/health
+
+# Test Celery task dispatch
+curl -X POST http://localhost:8000/test-task \
+  -H "Content-Type: application/json" \
+  -d '{"message": "Hello from test!"}'
+
+# Monitor Celery tasks
+docker-compose logs -f worker
+```
+
+
+## Key Implementation Notes
+
+### Python Standards
+- **Style**: PEP 8 compliance
+- **Documentation**: Google/NumPy docstring format
+- **Naming**: snake_case for variables and functions
+- **Testing**: pytest with test_i_can_xxx / test_i_cannot_xxx patterns
+
+### Dependencies Management
+- **Package Manager**: pip (standard)
+- **External Dependencies**: Listed in each service's requirements.txt
+- **Standard Library First**: Prefer standard library when possible
+
+### Testing Strategy
+- All code must be testable
+- Unit tests for each processing function
+- Integration tests for file processing workflow
+- Tests validated before implementation
+
+### Critical Architecture Decisions Made
+1. **Option Selected**: Single FastAPI service handles both API and file watching
+2. **Celery with Redis**: Chosen over other async patterns for scalability
+3. **EasyOCR Preferred**: Selected over Tesseract for modern OCR needs
+4. **Container Development**: Hot-reload setup required for development workflow
+
+### Development Process Requirements
+1. **Collaborative Validation**: All options must be explained before coding
+2. **Test-First Approach**: Test cases defined and validated before implementation
+3. **Incremental Development**: Start simple, extend functionality progressively
+4. **Error Handling**: Clear problem explanation required before proposing fixes
+
+### Next Implementation Steps
+1. Create docker-compose.yml with all services
+2. Implement basic FastAPI service structure
+3. Add watchdog file monitoring
+4. Create Celery task structure
+5. Implement document processing tasks
+6. Build React monitoring interface
