+## Commit Signature Verification
+
+For the security and integrity of our project, we require all contributors to sign their commits.  
+For detailed instructions on why and how to sign your commits refer to [GitHub's documentation on commit signature verification](https://docs.github.com/en/authentication/managing-commit-signature-verification/about-commit-signature-verification).
+
+> [!Note]
+> We recommend signing commits using an [SSH key](https://docs.github.com/en/authentication/managing-commit-signature-verification/about-commit-signature-verification#ssh-commit-signature-verification). Ensure your Git version supports SSH signature verification (Git 2.34 or later).
