+## 📝 Contribution Guidelines
+
+### Branching Strategy
+* **main**: The stable production branch. Do not commit directly here.
+* **feature/**: For new lessons or engine features.
+* **fix/**: For bug fixes.
+
+### Lesson Standards
+If you are writing a new lesson:
+* Start with a clear learning objective.
+* Use the `<InteractivePython>` component at least once per page for hands-on practice.
+* Ensure the code examples are compatible with Python 3 (Skulpt's current implementation).
+
+### Code Style
+* We use **Prettier** for formatting. Please run `npm run format` before submitting a PR.
+* React components should follow functional patterns and use hooks.
