+- **Language/Framework:** Not yet chosen
+- **Dependencies:** None
+- **Build system:** None
+- **Tests:** None
+- **CI/CD:** None
+- **Linting/Formatting:** None
+
+## Development Guidelines
+
+When adding code to this repository, follow these conventions:
+
+### General
+
+- Keep the repository well-organized with clear directory structure
+- Add a `.gitignore` appropriate to the chosen language/framework
+- Include meaningful commit messages that explain *why*, not just *what*
+
+### When Setting Up the Project
+
+1. Choose a language and framework, then add the appropriate config files
+2. Set up a package manager and declare dependencies
+3. Add linting and formatting tools from the start
+4. Configure a test framework and write tests alongside new code
+5. Add CI/CD pipeline configuration (e.g., GitHub Actions)
+6. Update this CLAUDE.md file as the project evolves
+
+### Code Quality
+
+- Write clean, readable code with self-documenting names
+- Keep functions small and focused on a single responsibility
+- Validate inputs at system boundaries (user input, external APIs)
+- Avoid premature abstraction — prefer simple, direct code
+
+### Testing
+
+- Write tests for new functionality
+- Run the full test suite before committing
+- Maintain test coverage as the project grows
+
