+General rules and guidelines
+============================
+
+This page contains guidelines relevant for contributing to any area of Godot.
+
+When contributing to any particular area, please refer to its respective guidelines additionally.
+
+Code of conduct
+---------------
+
+When you contribute to Godot, we expect that you respect our `Code of Conduct <https://godotengine.org/code-of-conduct/>`__.
+
+Contributing with AI and large language models
+----------------------------------------------
+
+The use of AI to contribute to Godot is discouraged.
+We acknowledge that AI can be useful, but we are convinced that effort by humans results in better and more relevant
+contributions.
+
+If you use AI to assist with your contribution, you are required to:
+
+- Understand and verify any of its solutions.
+    - If you don't understand the solution, do not submit it.
+- Proof read and edit anything it generates.
+    - Better, use AI to proof read something *you* create.
+- Disclose how and to what degree you used AI (in the issue description, pull request description, or otherwise).
+    - In particular, you must disclose if you used AI to write part of your contribution or issue / pull request description. Using translation software for text that you originally wrote is acceptable for issues and pull requests.
+
+As a rule of thumb, only submit code that you fully understand and are prepared to explain to a maintainer. Maintainers
+are spending their personal time reviewing your code, it is your job to ensure that the code you submit is well-tested
+and functional. Please be respectful of their time and only submit code that you have put thought and effort into.
+Contributions made entirely by AI are prohibited.
