## Markdown editions

Every canonical HTML page has a clean Markdown edition for automated readers.
For directory-style URLs, append `index.md`: `/tools/word-counter/` becomes
`/tools/word-counter/index.md`, and `/` becomes `/index.md`.

- [All Markdown editions in one file](https://candoya.com/llms-full.txt): English content from every canonical page.
