+# Contributing
+
+Thank you for your interest in contributing to Chai (:
+
+This document provides guidelines for contributing to the project.
+
+## Code Formatting
+
+This project uses **default rustfmt settings**. To ensure consistent code style across all contributions:
+
+1. **Check formatting locally** before pushing:
+
+   ```sh
+   cargo fmt -- --check
+   ```
+
+2. **Fix formatting** if the check fails:
+
+   ```sh
+   cargo fmt
+   ```
+
+3. **CI will block PRs** with incorrect formatting. Fix any issues before merging.
+
+**Important**: Do not create a `rustfmt.toml` file or override rustfmt settings. Chai uses the default configuration to ensure consistency.
+
+## Development Workflow
+
+1. Fork the repository
+2. Create a feature branch
+3. Make your changes
+4. Run `cargo fmt -- --check` to verify formatting
+5. Run `cargo build` and `cargo test` to verify everything works
+6. Submit a pull request and link it to the relevant issue
+
+## Questions?
+
+Feel free to open an issue if you have questions about contributing!
