 ## 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/awslabs/aws-data-wrangler/labels/help%20wanted) issues is a great place to start.
