 ## Stewards
 
-Stewards are contributors that are particularly involved, familiar, or responsive to certain areas of the project. Their role is to help provide context and guidance to others working on p5.js. If you have a question about contributing to a particular area, you can tag the listed steward in an issue or pull request. They may also weigh in on feature requests and guide the overall direction of their area, with the input of the community. You can read more about the organization of the project at [contributor_docs/organization.md](https://github.com/processing/p5.js/blob/main/contributor_docs/organization.md).
