+# Contributing to kagglehub
+
+First off, thanks for taking the time to contribute!
+
+All types of contributions are encouraged and valued.
+
+## Issues
+
+We use GitHub issues to track **public** bugs and feature requests. Please ensure your description is clear and has sufficient instructions to be able to reproduce the issue.
+
+If you found a bug or have a feature request, follow these instructions:
+
+* Open an [Issue](/issues/new).
+* Provide as much context as you can about what you're running into.
+* Provide project and platform versions (python, pip, kagglehub), depending on what seems relevant.
+
+## Pull Requests (PRs)
+
+We encourage everyone to open an issue first to discuss the general approach before opening a PR to reduce churns. If your solution to a bug you found is trivial, we also accept PRs directly.
+
+Please follow these best practices when opening a PR:
+
+* Use a **clear and descriptive title**.
+* If your PR adds a user-facing feature or fixes a bug, make sure to add an entry under the "Next Release" section in the [CHANGELOG.md](CHANGELOG.md)
+* If your PR fixes a specific issue, add `Fixes #<ISSUE_NUMBER>` to your PR's description.
+* Include screenshots/console output of the behavior before and after the fix.
+* Include instructions on how to reproduce the issue and test the fixes.
