+## Finding ways to help
+
+We label issues that would be good for a first time contributor as [`good first issue`](https://github.com/RustPython/RustPython/issues?q=label%3A%22good+first+issue%22+is%3Aissue+is%3Aopen+).
+Also checkout the [issue tracker](https://github.com/RustPython/RustPython/issues) for all open issues. 
+
+You can enhance CPython compatibility by increasing our unittest coverage, you can see [This pinned issue](https://github.com/RustPython/RustPython/issues/6839) to see which libs and tests need be updated to our current supported python version.
+
+Another approach is to checkout the source code: builtin functions and object
+methods are often the simplest and easiest way to contribute.
+
+You can also simply run `python -I scripts/whats_left.py` to assist in finding any unimplemented method.
+
+## Use of AI
+
+We **require all use of AI in contributions to follow our
+[AI Policy](https://github.com/RustPython/.github/blob/main/AI_POLICY.md)**.

+If your contribution does not follow the policy, it will be closed.
