+# Sandbox Docker Environments
+
+This directory contains multiple Docker environment configurations for different use cases.
+
+## Available Environments
+
+### Default Environment
+- **File**: `../packages/sandbox/Dockerfile`
+- **Size**: ~200MB
+- **Languages**: JavaScript, TypeScript
+- **Use Cases**: Basic JS/TS execution, lightweight applications
+
+### Python Data Science
+- **File**: `python-data-science.dockerfile`
+- **Size**: ~2.5GB
+- **Languages**: Python, JavaScript, TypeScript
+- **Packages**: numpy, pandas, matplotlib, scikit-learn, torch, transformers, jupyter
+- **Use Cases**: 
+  - Data analysis and visualization
+  - Machine learning model training
+  - Jupyter notebook execution
+  - AI/ML prototyping
+
+### Node Extended
+- **File**: `node-extended.dockerfile`
+- **Size**: ~1.2GB
+- **Languages**: JavaScript, TypeScript, Python
+- **Packages**: express, fastify, mongoose, prisma, webpack, jest, cypress
+- **Use Cases**:
+  - Full-stack web development
+  - API development
+  - Testing and CI/CD
+  - Build tool workflows
+
+### Multi-Language
+- **File**: `multi-lang.dockerfile`
+- **Size**: ~4GB
+- **Languages**: Python, JavaScript, TypeScript, Go, Java, Rust, Ruby, R
+- **Use Cases**:
+  - Cross-language development
+  - Polyglot applications
+  - Language comparison and testing
+  - Educational environments
+
+## How to Use
+
+### Environment Variable
+```bash
+export SANDBOX_ENVIRONMENT=python-data-science
+docker build -f dockerfiles/python-data-science.dockerfile .
+```
+
+### Configuration File
+Create `.sandbox-config.json` in your project root:
+```json
+{
+  "environment": "node-extended"
+}
+```
+
+### CLI Flag (if supported by your tooling)
+```bash
+sandbox-cli --environment multi-lang
+```
+
+## Building Images
+
+### Python Data Science
+```bash
+docker build -f dockerfiles/python-data-science.dockerfile -t sandbox-python-ds .
+docker run -p 3000:3000 sandbox-python-ds
+```
+
+### Node Extended
+```bash
+docker build -f dockerfiles/node-extended.dockerfile -t sandbox-node-ext .
+docker run -p 3000:3000 sandbox-node-ext
+```
+
+### Multi-Language
+```bash
+docker build -f dockerfiles/multi-lang.dockerfile -t sandbox-multi-lang .
+docker run -p 3000:3000 sandbox-multi-lang
+```
+
+## Performance Considerations
+
+| Environment | Build Time | Image Size | Memory Usage |
+|-------------|------------|------------|--------------|
+| Default | ~2 min | ~200MB | ~50MB |
+| Python Data Science | ~8 min | ~2.5GB | ~300MB |
+| Node Extended | ~5 min | ~1.2GB | ~150MB |
+| Multi-Language | ~12 min | ~4GB | ~500MB |
+
+## Choosing the Right Environment
+
+- **Default**: For simple JavaScript/TypeScript tasks
+- **Python Data Science**: For ML, data analysis, or scientific computing
+- **Node Extended**: For web development with comprehensive tooling
+- **Multi-Language**: For polyglot development or when language requirements are unknown
+
+## Customization
+
+You can extend any of these environments by:
+
+1. Creating a new dockerfile that uses one as a base:
+```dockerfile
+FROM sandbox-python-ds
+RUN pip install your-custom-package
+```
+
+2. Modifying the existing dockerfiles to add specific packages
+3. Creating environment-specific configuration files
