+
+## Development Workflow
+
+### Working with Jupyter Notebooks
+1. Start Jupyter in the repository root: `jupyter notebook`
+2. Navigate to the desired lesson folder
+3. Open `.ipynb` files to work through exercises
+4. Notebooks are self-contained with explanations and code cells
+5. Most notebooks use pandas, numpy, and matplotlib - ensure these are installed
+
+### Lesson Structure
+Each lesson typically contains:
+- `README.md` - Main lesson content with theory and examples
+- `notebook.ipynb` - Hands-on Jupyter notebook exercises
+- `assignment.ipynb` or `assignment.md` - Practice assignments
+- `solution/` folder - Solution notebooks and code
+- `images/` folder - Supporting visual materials
+
+### Quiz Application Development
+- Vue.js 2 application with hot-reload during development
+- Quizzes stored in `quiz-app/src/assets/translations/`
+- Each language has its own translation folder (en, fr, es, etc.)
+- Quiz numbering starts at 0 and goes up to 39 (40 quizzes total)
+
+### Adding Translations
+- Translations go in `translations/` folder at repository root
+- Each language has complete lesson structure mirrored from English
+- Automated translation via GitHub Actions (co-op-translator.yml)
+
+## Testing Instructions
+
+### Quiz Application Testing
+```bash
+cd quiz-app
+
+# Run lint checks
+npm run lint
+
+# Test build process
+npm run build
+
+# Manual testing: Start dev server and verify quiz functionality
+npm run serve
+```
+
+### Notebook Testing
+- No automated test framework exists for notebooks
+- Manual validation: Run all cells in sequence to ensure no errors
+- Verify data files are accessible and outputs are generated correctly
+- Check that visualizations render properly
+
+### Documentation Testing
+```bash
+# Verify Docsify renders correctly
+docsify serve
+
+# Check for broken links manually by navigating through content
+# Verify all lesson links work in the rendered documentation
+```
+
+### Code Quality Checks
+```bash
+# Vue.js projects (quiz-app and visualization projects)
+cd quiz-app  # or visualization project folder
+npm run lint
+
+# Python notebooks - manual verification recommended
+# Ensure imports work and cells execute without errors
+```
+
+## Code Style Guidelines
+
+### Python (Jupyter Notebooks)
+- Follow PEP 8 style guidelines for Python code
+- Use clear variable names that explain the data being analyzed
+- Include markdown cells with explanations before code cells
+- Keep code cells focused on single concepts or operations
+- Use pandas for data manipulation, matplotlib for visualization
+- Common import pattern:
+  ```python
+  import pandas as pd
+  import numpy as np
+  import matplotlib.pyplot as plt
+  ```
+
+### JavaScript/Vue.js
+- Follow Vue.js 2 style guide and best practices
+- ESLint configuration in `quiz-app/package.json`

+- Pre-lesson quizzes test prior knowledge
+- Post-lesson quizzes reinforce learning
+- Assignments provide hands-on practice
+- Sketchnotes provide visual summaries
+
+### Troubleshooting Common Issues
+
+**Jupyter Kernel Issues:**
+```bash
+# Ensure correct kernel is installed
+python -m ipykernel install --user --name=datascience
+```
+
+**npm Install Failures:**
+```bash
+# Clear npm cache and retry
+npm cache clean --force
+rm -rf node_modules package-lock.json
+npm install
+```
+
+**Import Errors in Notebooks:**
+- Verify all required libraries are installed
+- Check Python version compatibility (Python 3.7+ recommended)
+- Ensure virtual environment is activated
+
+**Docsify Not Loading:**
+- Verify you're serving from repository root
+- Check that `index.html` exists
+- Ensure proper network access (port 3000)
+
+### Performance Considerations
+- Large datasets may take time to load in notebooks
+- Visualization rendering can be slow for complex plots
+- Vue.js dev server enables hot-reload for quick iteration
+- Production builds are optimized and minified
+
+### Security Notes
+- No sensitive data or credentials should be committed
+- Use environment variables for any API keys in cloud lessons
+- Azure-related lessons may require Azure account credentials
+- Keep dependencies updated for security patches
+
+## Contributing to Translations
+- Automated translations managed via GitHub Actions
+- Manual corrections welcomed for translation accuracy
+- Follow existing translation folder structure
+- Update quiz links to include language parameter: `?loc=fr`
+- Test translated lessons for proper rendering
