+# Contributing to the Repository
+
+We welcome contributions to the repository! Of course, your contributions will be credited. If you’d like to add solutions in a language of your choice, or amend an existing solution in any language, here’s how you can contribute.
+
+1. Let me know what you plan to contribute! The best way to do this is by joining our discord server (see page 2 of the book). Communication is important to prevent you labouring on a set of quesitons that someone's already working on.
+
+2. Once you've been approved, **fork the repository** to start working on your own solutions locally.
+
+3. Take a close look at how the Python solutions are organized. Your contributions should align with this structure (e.g., folder organization, file naming). 
+
+4. Always **create a new branch** for your additions or changes. We recommend creating separate branches for each chapter or feature you’re contributing. Example: `git checkout -b java-solutions-linked-lists`.
+
+5. Stay true to existing code comments and structure. Feel free to add additional comments for clarity, especially if any language-specific nuances are included.
+
+6. **Test your code**. Be sure your code runs. We're currently working on making all test cases public. In the mean time, please use your own set of diverse test cases.
+
+7. **Open a pull request** (PR) and clearly describe your work in the PR. Respond to comments and make necessary adjustments when requested. Once approved, your PR will be merged!
+
+## Questions or Issues?
+If you encounter any issues or have questions about contributing, feel free to reach out via the discord, or email us at [email protected].
+
+We greatly appreciate you helping us build this repository and making it accessible to more people. Thank you for contributing!
