During a project I was given a folder with a number of documents written in markdown. I'm not familar with how you read markdowns in text editors but this resource helps to put it in a more readable format.

I found this site after speaking to Jayne Schurick and Whitney Quesenbery about accessibility. It gives developers links to resources that can help make website content more accessible. I was especially interested in the sonification framework which makes it easier to "create sound-based representations of interactive data..." I think it's definitely worth exploring.
