So, this is why I don’t like people trying to “simplify” WCAG. Stark did it and I only looked at its 1.1.1 Non-Text Content page.
Several notes:
1. I don’t think this is much clearer than 1.1.1 itself. There is more fluff, but I don’t think it’s super useful
2. It calls the Success Criterion “Guideline” under the “What:” heading
3. It names transcripts/captions, which are only tangential to the SC at hand
4. No info that decorative images must be ignored
