+# Contributing to thirdweb Unity SDK
+
+We warmly welcome contributions to the thirdweb Unity SDK! If you're looking to contribute, here's how you can get started.
+
+## How to Contribute
+
+1. Fork the Repository: Click the "Fork" button at the top right of this page to create your own copy of the repository.
+2. Clone Your Fork: Clone your fork to your local machine for development.
+3. Create a Feature Branch: Make a new branch for your changes. This helps keep contributions organized.
+4. Make Your Changes: Work on your changes. Make sure they are well-tested and don't break existing functionality.
+5. Commit Your Changes: Commit your changes with a clear and descriptive commit message.
+6. Push to Your Fork: Push your changes to your forked repository.
+7. Submit a Pull Request: From your fork, submit a pull request to our main repository. Provide a clear description of your changes and any relevant issue numbers.
+
+Notes: 
+- For WebGL-specific contributions, you may contribute to our [JS](https://github.com/thirdweb-dev/js/) package as well. The bulk of WebGL-specific behavior goes through its Unity bridge.
+- For new Wallet Provider contributions, see our guide to [Submit your Wallet](https://portal.thirdweb.com/unity/wallets/submission).
+
+## Guidelines
+
+- Keep It Simple: Try to keep your contributions small and simple. This makes them easier to review and merge.
+- Supported Platforms: Make sure your changes work on either WebGL only, Native platforms only, or both. A good test is to build `Scene_Prefabs` to test your changes there. 
+- Test Your Code: Ensure your code works as expected and doesn't introduce new issues.
+- Be Respectful: When discussing changes, always be respectful and constructive.
