Question

This is the final level, the goal is to contribute to this repository by making a pull request on GitHub. Please note that this level is designed to encourage you to add a valid contribution to Githug, not testing your ability to create a pull request. Contributions that are likely to be accepted are levels, bug fixes and improved documentation.

这是最后一关，目标是让你在 Github 上提交一个 pull request 贡献。设计本关的目的就是鼓励你向 Githug 提交贡献，而不是测试你使用 pull request 的技能。贡献包括新的关卡、修复 BUG 和改善文档。

恭喜通关！
