- Clear and easy to see (preferably in high resolution)

- Try to keep the videos short. 3-10 minutes is optimal.
- If the content takes longer, try to break it up into segments.

- If a document (like a PDF) isn't searchable, an accompanying text version should be made available.
- Any table or chart should have identifying headers and labels, as well as summaries.
