 # KYB Dots.OCR Text Extraction
 
-This Hugging Face Space provides a FastAPI endpoint for text extraction from identity documents using Dots.OCR with ROI (Region of Interest) support.
+This [Hugging Face Space](https://huggingface.co/docs/hub/spaces) provides a FastAPI endpoint for text extraction from identity documents using Dots.OCR with ROI (Region of Interest) support. Built as a Docker Space for maximum flexibility and performance.
 
-## Features
+## 🚀 Quick Start
 
-- **Text Extraction**: Extract text from identity documents using Dots.OCR
-- **ROI Support**: Process pre-cropped images or full images with ROI coordinates
-- **Field Mapping**: Structured field extraction with confidence scores
-- **MRZ Detection**: Machine Readable Zone data extraction
-- **Standardized API**: Consistent response format for integration
+### Using the API
+1. **Upload an image** (JPEG, PNG, or other supported formats)
+2. **Optionally specify ROI** coordinates for targeted extraction
+3. **Get structured results** with confidence scores and field mapping
 
-## API Endpoints
+### Test the API
+```bash
+# Basic OCR test
+curl -X POST https://algoryn-dots-ocr-idcard.hf.space/v1/id/ocr \
+  -F "file=@test_image.jpg"
 
-### Health Check
+# With ROI (region of interest)
+curl -X POST https://algoryn-dots-ocr-idcard.hf.space/v1/id/ocr \
+  -F "file=@test_image.jpg" \
+  -F 'roi={"x1":0.1,"y1":0.1,"x2":0.9,"y2":0.9}'
 ```

-## Usage
+## 🛠️ Deployment to Hugging Face Spaces
 
-1. Upload an image file (JPEG, PNG)
-2. Optionally provide ROI coordinates as JSON string
-3. Receive structured field extraction results
+### Prerequisites
+- [Hugging Face CLI](https://huggingface.co/docs/hub/install-huggingface-cli) installed
+- Docker installed locally (for testing)
 
-## Environment Variables
+### 1. Create HF Space
+```bash
+# Login to Hugging Face
+huggingface-cli login
+
+# Create a new Docker Space
+huggingface-cli repo create dots-ocr-idcard --type space --space_sdk docker --organization algoryn
+```
 
+### 2. Clone and Setup
+```bash
+# Clone the space locally
+git clone https://huggingface.co/spaces/algoryn/dots-ocr-idcard
+cd dots-ocr-idcard
+
+# Copy required files
+cp /path/to/kybtech-ml-pipelines/docker/hf/dots-ocr/* .
+
+# Copy field extraction module
+mkdir -p src/idcard_api
+cp /path/to/kybtech-ml-pipelines/src/idcard_api/field_extraction.py src/idcard_api/
+touch src/idcard_api/__init__.py
+```
+
+### 3. Deploy
+```bash
+git add .
+git commit -m "Deploy Dots-OCR text extraction service"
+git push
+```
+
+### 4. Test Deployment
+The Space will be available at `https://algoryn-dots-ocr-idcard.hf.space` after deployment (usually 5-10 minutes).
+
+## ⚙️ Configuration
+
+### Environment Variables
 - `HF_DOTS_MODEL_PATH`: Path to Dots.OCR model weights
 - `HF_DOTS_CONFIDENCE_THRESHOLD`: Confidence threshold for field extraction
 - `HF_DOTS_DEVICE`: Device to use (auto, cpu, cuda)
 - `HF_DOTS_MAX_IMAGE_SIZE`: Maximum image size for processing
 - `HF_DOTS_MRZ_ENABLED`: Enable MRZ detection
 
-## Performance
+### Hugging Face Spaces Settings
+- **SDK**: Docker
+- **Port**: 7860 (default)
+- **Hardware**: CPU (upgradeable to GPU)
+- **Storage**: Persistent storage available for model caching
+
+## 📊 Performance
 
-- **GPU**: 300-900ms processing time
-- **CPU**: 3-8s processing time
-- **Memory**: ~6GB per instance
+| Hardware | Processing Time | Memory Usage |
+|----------|----------------|--------------|
+| **GPU** | 300-900ms | ~6GB |
+| **CPU** | 3-8s | ~2GB |

-# Dots-OCR Text Extraction Service - HF Deployment
-
-## Quick Deploy to Hugging Face Spaces
-
-### 1. Create HF Space
-```bash
-# Login to Hugging Face
-huggingface-cli login
-
-# Create a new Space
-huggingface-cli repo create dots-ocr-idcard --type space --space_sdk docker --organization algoryn
-```
-
-### 2. Prepare for Deployment
-```bash
-# Clone the space locally
-git clone https://huggingface.co/spaces/algoryn/dots-ocr-idcard
-cd dots-ocr-idcard
-
-# Copy required files
-cp /path/to/kybtech-ml-pipelines/docker/hf/dots-ocr/* .
-
-# Copy field extraction module (needed for structured extraction)
-mkdir -p src/idcard_api
-cp /path/to/kybtech-ml-pipelines/src/idcard_api/field_extraction.py src/idcard_api/
-touch src/idcard_api/__init__.py
-```
-
-### 3. Create app.py if needed
-The app.py file should already exist. Key features:
-- `/health` endpoint for health checks
-- `/v1/id/ocr` endpoint for text extraction
-- Supports ROI (Region of Interest) cropping
-- Structured field extraction
-- MRZ extraction support
-
-### 4. Push to HF
-```bash
-git add .
-git commit -m "Deploy Dots-OCR text extraction service"
-git push
-```
-
-### 5. Test the Deployment
-Once deployed (usually takes 5-10 minutes), test with:
-```bash
-# Basic OCR test
-curl -X POST https://algoryn-dots-ocr-idcard.hf.space/v1/id/ocr \
-  -H "Authorization: Bearer YOUR_HF_TOKEN" \
-  -F "file=@test_image.jpg"
-
-# With ROI (region of interest)
-curl -X POST https://algoryn-dots-ocr-idcard.hf.space/v1/id/ocr \
-  -H "Authorization: Bearer YOUR_HF_TOKEN" \
-  -F "file=@test_image.jpg" \
-  -F 'roi={"x1":0.1,"y1":0.1,"x2":0.9,"y2":0.9}'
-```
-
-## Environment Variables
-No special environment variables needed. The service runs on port 7860 by default.
-
-## Notes
-- Service includes mock mode if Dots-OCR fails to load
-- Health check available at `/health`
-- Structured field extraction included
-- MRZ parsing support built-in
