+Thank you for contributing to `PHEvaluator`! Here are some advices might be useful for passing the code review.
 
+* Check out the latest code in `develop` branch. Also target your Pull Request on the `develop` branch.
 * The Coding Style is to use 2-space indentations in C++, and 4-space indentations in Python. An [.editorconfig](https://github.com/HenryRLee/PokerHandEvaluator/blob/master/.editorconfig) file has also been created, which [most editors support natively](https://editorconfig.org/).
 * Split your work into multiple Pull Request if they are irrelevant, so that we can merge them independently (usually with squash merge).
+* If you are planning to work on a large feature, it'd be helpful if we can understand your idea first, prior to getting your hands on the implementation. You may create a new issue or a new discussion.
