 ## Finding contributions to work on
+Looking at the existing issues is a great way to find something to contribute on. As our projects, by default, use the default GitHub issue labels (enhancement/bug/duplicate/help wanted/invalid/question/wontfix), looking at any ['help wanted'](https://github.com/aws-actions/configure-aws-credentials/labels/help%20wanted) issues is a great place to start.

-## Automated Tools
-
-The use of AI tooling for assisted development work is accepted and encouraged

-
-- All issue and pull request submissions to this repository that are sourced by
-  AI must first be reviewed by a human before submitting to the repository.
-  Items reviewed in this way must include a statement like "generated by AI
-  tools, and reviewed by [person]"
-- Please ensure that your submissions are actually improvements. While we are
-  grateful for any proposed fixes, even if they are very small, behavior that
-  looks like creating noisy PRs or artificially inflating submission counts
-  is not acceptable.
-- We may close issues or pull requests, or limit your ability to interact with
-  this repository, for behavior that in our estimation violates these rules or
-  any of the other rules in this repository's
-  [Code of Conduct](CODE_OF_CONDUCT.md).
