# Dewey blog

Practical guides to documentation for people and coding agents.

- [Add Dewey to an existing repository without replacing its documentation](https://deweydocs.com/blog/add-dewey-to-existing-documentation.md): Adopt Dewey in a repository with existing docs, inspect the generated regions and document kinds, and preserve authored rules and guides.
- [Catch documentation drift after a code change](https://deweydocs.com/blog/catch-documentation-drift-after-code-changes.md): Use source maps and explicit reviews to catch documentation that needs another look after code changes, with a complete Dewey example.
- [How to keep AGENTS.md useful as a repository grows](https://deweydocs.com/blog/keep-agents-md-useful.md): Keep AGENTS.md short and useful with source maps, explicit rules, and commands that find the right documentation for a code change.
- [Publish Markdown documentation for people and agents from one source](https://deweydocs.com/blog/markdown-docs-for-people-and-agents.md): Build HTML, Markdown copies, llms.txt, and a full-text bundle from one documentation source while keeping implementation maps separate.
