+## Use of Generative AI Tools
+
+Generative AI tools have evolved rapidly, and their suggested results can be helpful.
+As with using any tool, the resulting contribution is the responsibility of the contributor.
+We value good code, concise and accurate documentation, and avoiding unnecessary code churn.
+Discretion, good judgment, and critical thinking are the foundation of all good contributions, regardless of the tools used in their creation.
