 - Following [Web Content Accessibility Guidelines](https://www.w3.org/TR/WCAG21/) in our tools and working towards making it easier for users to follow them in their projects
 - Making p5.js error messages more helpful and supportive to people using the tool (e.g., the [p5.js Friendly Error System (FES)](./friendly_error_system.md))
 - Mentoring and supporting learners of p5.js within communities that are historically excluded from and marginalized in creative coding and the digital arts

 - Publishing documentation and reports of our work that follow WCAG guidelines, use plain language, and focus on beginners from diverse experiences (e.g., [OSACC p5.js Access Report](https://github.com/processing/OSACC-p5.js-Access-Report))
