Why documentation is a secret weapon for accessibility

When we talk about improving accessibility, we often focus on audits, design tweaks, or updates to code. However, one of the most powerful long-term moves your team can make is documenting what you learn.

Why documentation matters

Centralized knowledge sharing. Whether you’re using WordPress, Squarespace, or a custom CMS, having a shared document library that outlines your accessibility standards, decisions, and processes keeps everyone aligned, from content editors and designers to developers.

Preserve institutional knowledge. Relying on one person who “knows accessibility” creates risk. If they leave or go on vacation, your strategy goes with them. Documentation captures that institutional and technical knowledge so it lives beyond any individual team member.

Build a living knowledge base. Think of it as an internal guidebook that grows with your team. Over time, this resource can include everything from color contrast tools and alt text guidance to code snippets and testing checklists.

Start small

If you’re just starting out, try this: Pick one accessibility decision you made this week – maybe how you format headings or choose link text – and write it down in a shared document. That’s it. You’re building the habit.

Accessibility isn’t a one-time fix. It’s a team practice, and documentation is what helps that practice stick.
