FAQ

Absolutely! As an open-source project, we welcome contributions to the code base, test automation capabilities, and content library (test cases and remediation strategies). Visit our GitHub repository for contribution guidelines.

The application receives regular updates to incorporate new accessibility standards, improve testing methodologies, and enhance the user experience. As an open-source project, the development pace is driven by both the core team and community contributions.
