# Course summary

<br />

Technical Writing for Accessibility focused on the following ideas:

- Accessibility in documentation benefits people with permanent, temporary, or situational disabilities.
- Every image requires an alt text element. Alt text acts as a functional equivalent for an image by providing a concise summary of the image's purpose and context.
- Sufficient color contrast helps readers with color blindness or low vision.
- Write for a broad spectrum of readers.
- Avoid relying only on visual indicators, such as colors or patterns, to communicate important information.
- Practice editing for accessibility to ensure proper heading structure, descriptive link text, and clear language.
