You know it's important for your web project to be accessible to people who use all kinds of assistive technology to access the internet. But all the guidelines for web accessibility you can find don't go much beyond "make sure all your images have alt text", and all the resources you can find treat "accessibility" as a synonym for "making your site work in a screen reader". You know there are other things you should be doing and other forms of assistive technology you should be accomodating, but all the best practices documents are a complicated morass of contradicting information (if you can find best practices documents at all.)
Have no fear! This tutorial gives you a number of concrete steps to take to make things more accessible.
