The first iteration of the CivicActions Accessibility Playbook is now available for public use. This is an evolving effort, and we will continue to update it based on community feedback and internal efforts to improve its usefulness.
To contribute to the playbook:
Mike Gifford is a CivicActions Accessibility team member and a Drupal Core Accessibility Maintainer. He has been actively involved in the accessibility unconference community and founder of Ottawa's A11yYOW meetup. He's also completed the DHS Section 508 Standards for Web certification.
