[mjang]

Is your feature request related to a problem? Please describe

Readability is important for our users. It's a problem suitable for a wide variety of technical writers at a hackathon. We want issues that are suitable for writers who may not know Git or Vale.

Describe the solution you'd like

Issues suitable for hackathons at venues such as the Write the Docs NA conference. Next scheduled for early May, 2025.

• Set up issues by page
• Set criteria suitable for an accessible readability measure, e.g. the Hemingway App
