Accessibility can be a complex and difficult topic. The Accessibility Project understands this and wants to help make it easier to implement on the web. Our goal is to accomplish this with three principles in mind:

1. Digestible. We strive to feature short, digestible pieces of content.
2. Up-to-date. The project is hosted on GitHub so information can be current with the latest standards.
3. Forgiving. People make mistakes, so we seek to be encouraging.

This is a great resource that lists which ServiceWorker features are supported by which major browsers.

Awareness comes first.
