+      value: |
+        Common reasons for proposals include:
+
+        - Altering the infrastructure;
+        - Bumping a critical dependency's major version;
+        - A significant improvement in user-friendliness;
+        - Significant refactor;
+        - ...
+
+        Please note this is not for feature request or bug template; such action could make us identify the issue wrongly and close it without doing anything.
+
+        We give you maximum freedom to write an elaborated proposal illustrating why you think the change is beneficial for us, and what steps we should take to turn this into reality.

+        If you do check this box, please send a pull request within 7 days after a maintainer's approval so we can still delegate this to someone else.
+
+        Proposals usually involve significant code changes, so please reach consensus with the maintainers before rushing to implement it, and make sure you follow the [Contributing Guidelines](https://github.com/hpcaitech/ColossalAI/blob/main/CONTRIBUTING.md).
+        This ensures that you don't waste your time and we don't waste ours reading the large diffs.
