+# Contribution guidelines
+
+Thank you for considering contributing to Mousefood!
+
+## Reporting issues
+
+1. Before submitting a new issue, please search the
+   [issue tracker](https://github.com/ratatui/mousefood/issues) using relevant
+   keywords to ensure it hasn't already been reported.
+
+## Pull requests
+
+1. Please include as much detail as possible in your pull request description
+   and follow the provided template. Be sure to highlight any changes that may
+   need special attention or that you're unsure about.
+2. If your idea could significantly impact the crate or its users, it's best to
+   discuss it in an issue first.
+3. Try to keep each pull request focused on a single change.
+4. Avoid mixing refactoring or reformatting with behavioral changes. Consider
+   splitting such changes into separate PRs.
+5. Run `cargo fmt` before committing.
+6. Use Conventional Commits for commit messages (for example, `feat: add foo`
+   or `fix: handle bar edge case`).
+7. Keep PR titles concise and aligned with Conventional Commits so they are
+   easy to scan (for example, `docs: update contributing`).
