+# Customizing Presidio Docker Images
+
+## Overview
+
+This guide provides detailed instructions on how to build and customize Presidio Docker images to support additional languages and custom configurations. The official Presidio Docker images support English by default, but you can create custom images to work with other languages.
+
+## Prerequisites
+
+- Docker installed ([Download Docker](https://docs.docker.com/get-docker/))
+- Basic knowledge of Docker and YAML
+- Familiarity with spaCy language models
+
+## Understanding Presidio's Docker Architecture
+
+Presidio consists of three main Docker images:
+- `presidio-analyzer`: Detects PII entities in text
+- `presidio-anonymizer`: Anonymizes detected PII
+- `presidio-image-redactor`: Redacts PII from images
+
+For multi-language support, you'll primarily need to customize the `presidio-analyzer` image.
+
+## Step 1: Clone the Presidio Repository
+
+First, clone the Presidio repository:
+
+```bash
+git clone https://github.com/microsoft/presidio.git
+cd presidio
+```
+
+## Step 2: Locate Configuration Files
+
+The key files for customization are:
+
+- `presidio-analyzer/Dockerfile`: Defines the analyzer Docker image
+- `presidio-analyzer/presidio_analyzer/conf/default_recognizers.yaml`: Configures recognizers
+
+## Step 3: Modify the Dockerfile for Additional Languages
+
+Navigate to `presidio-analyzer/Dockerfile` and add your desired spaCy language models.
+
+### Example: Adding Spanish Support
+
+In the Dockerfile, locate the section where spaCy models are downloaded and add:
+
+```dockerfile
+RUN python -m spacy download es_core_news_md
+```
+
+### Example: Adding Multiple Languages
+
+```dockerfile
+# Install language models
+RUN python -m spacy download en_core_web_lg
+RUN python -m spacy download es_core_news_md  # Spanish
+RUN python -m spacy download fr_core_news_md  # French
+RUN python -m spacy download de_core_news_md  # German
+```
+
+## Step 4: Configure Language Support
+
+### Update Configuration File
+
+Modify the recognizers configuration to support your languages. Edit `presidio-analyzer/presidio_analyzer/conf/default_recognizers.yaml`:
+
+```yaml
+# Add supported languages
+supported_languages:
+  - en
+  - es
+  - fr
+  - de
+```
+
+## Step 5: Build the Custom Docker Image
+
+Build your customized Docker image:
+
+```bash
+cd presidio-analyzer
+docker build . -t presidio-analyzer-custom:latest
+```
+
+## Step 6: Run Your Custom Image
+
+Run the custom image:
+
+```bash
+docker run -d -p 5002:3000 presidio-analyzer-custom:latest
+```
+
+## Common Pitfalls and Best Practices
+
+### 1. Memory Issues with Multiple Languages
+
+**Problem**: Adding 10+ languages at once can cause the Docker image to run out of memory during build or runtime.
+
+**Solutions**:
+- Use smaller spaCy models (e.g., `es_core_news_sm` instead of `es_core_news_lg`)
+- Increase Docker memory allocation:
+  ```bash
+  docker run -d -p 5002:3000 --memory="4g" presidio-analyzer-custom:latest
+  ```
+- Build images with only the languages you actually need
+- Consider using transformers models which can be more memory-efficient
+
+### 2. Warning: NLP Recognizer Not in List
+
+If you see warnings like:
+```
+UserWarning: NLP recognizer (e.g. SpacyRecognizer, StanzaRecognizer) is not in the list of recognizers for language en.
+```
+
+**Solution**: Ensure your language configuration matches your installed models:
+
+1. Check `default_recognizers.yaml` includes your language
+2. Verify the spaCy model is properly downloaded in the Dockerfile
+3. Ensure the language code matches (e.g., 'en' for English, 'es' for Spanish)
+
+### 3. Model Size vs. Accuracy Trade-off
+
+spaCy offers different model sizes:
+- `sm` (small): ~15MB, faster but less accurate
+- `md` (medium): ~40MB, balanced
+- `lg` (large): ~500MB+, most accurate but resource-intensive
+
+**Recommendation**: Start with `md` models for a good balance.
+
+## Complete Example: Building a Multi-Language Analyzer
+
+Here's a complete example for Spanish and French support:
+
+### Modified Dockerfile
+
+```dockerfile
+FROM python:3.11-slim
+
+WORKDIR /usr/bin/presidio-analyzer
+
+# Copy requirements
+COPY requirements.txt .
+RUN pip install -r requirements.txt
+
+# Install spaCy language models
+RUN python -m spacy download en_core_web_lg
+RUN python -m spacy download es_core_news_md
+RUN python -m spacy download fr_core_news_md
+
+# Copy application code
+COPY . .
+
+EXPOSE 3000
+
+CMD ["python", "app.py"]
+```
+
+### Test Your Custom Image
+
+```bash
+# Build the image
+docker build -t my-presidio-analyzer .
+
+# Run the container
+docker run -d -p 5002:3000 my-presidio-analyzer
+
+# Test with curl
+curl -X POST http://localhost:5002/analyze \
+  -H "Content-Type: application/json" \
+  -d '{"text": "Mi nombre es David y mi email es david@example.com", "language": "es"}'
+```
+
+## Using Docker Compose
+
+For complex setups, use docker-compose.yml:
+
+```yaml
+version: '3.8'
+services:
+  presidio-analyzer:
+    build:
+      context: ./presidio-analyzer
+    ports:
+      - "5002:3000"
+    environment:
+      - LOG_LEVEL=INFO
+    deploy:
+      resources:
+        limits:
+          memory: 4G
+  
+  presidio-anonymizer:
+    image: mcr.microsoft.com/presidio-anonymizer:latest
+    ports:
+      - "5001:3000"
+```
+
+Run with:
+```bash
+docker-compose up --build
+```

+
+## Troubleshooting
+
+### Issue: Build fails with "No space left on device"
+**Solution**: Clean up Docker resources:
+```bash
+docker system prune -a
+```
+
+### Issue: Container crashes on startup
+**Solution**: Check logs and increase memory:
+```bash
+docker logs <container-id>
+docker run --memory="6g" ...
+```
