+# Clean Code Guidelines
+
+## Constants Over Magic Numbers
+- Replace hard-coded values with named constants
+- Use descriptive constant names that explain the value's purpose
+- Keep constants at the top of the file or in a dedicated constants file
+
+## Meaningful Names
+- Variables, functions, and classes should reveal their purpose
+- Names should explain why something exists and how it's used
+- Avoid abbreviations unless they're universally understood
+
+## Smart Comments
+- Don't comment on what the code does - make the code self-documenting
+- Use comments to explain why something is done a certain way
+- Document APIs, complex algorithms, and non-obvious side effects
+
+## Single Responsibility
+- Each function should do exactly one thing
+- Functions should be small and focused
+- If a function needs a comment to explain what it does, it should be split
+
+## DRY (Don't Repeat Yourself)
+- Extract repeated code into reusable functions
+- Share common logic through proper abstraction
+- Maintain single sources of truth
+
+## Clean Structure
+- Keep related code together
+- Organize code in a logical hierarchy
+- Use consistent file and folder naming conventions
+
+## Encapsulation
+- Hide implementation details
+- Expose clear interfaces
+- Move nested conditionals into well-named functions
+
+## Code Quality Maintenance
+- Refactor continuously
+- Fix technical debt early
+- Leave code cleaner than you found it
+
+## Testing
+- Write tests before fixing bugs
+- Keep tests readable and maintainable
+- Test edge cases and error conditions
+
+## Version Control
+- Write clear commit messages
+- Make small, focused commits
+- Use meaningful branch names
