llms.txt of a manual 

Every manual is rendered with an llms.txt at its root, following the llms.txt convention: where a language model starts reading the manual. It is Markdown, and names what a client could not find without knowing the names of our files:

# TCA Reference

> Version main of this manual.
> Every page is also available as Markdown: the same path with .md instead of .html.
> The permalink of an anchor is https://docs.typo3.org/permalink/t3tca:{anchor}@main.

## Indexes

- [toc.json](toc.json): Table of contents: every page in order, with its title and permalink anchor
- [classes.json](classes.json): Every PHP class the manual speaks of, and where
- [objects.inv.json](objects.inv.json): Every link target, as the interlinks of other manuals use them

## Pages

- [TCA Reference](Index.md)
  - [Introduction](Introduction/Index.md)
  …

Only the indexes the render wrote are listed: a manual without options names no confvals.json. The pages are those its table of contents leads to, nested as there, and linked as Markdown where the manual was rendered to Markdown.

The pages no table of contents leads to are listed under "Other pages", the 404 page first: the official manuals keep there what was removed, by TYPO3 version, with what replaces it, and old anchors and permalinks lead there. A page without a title is left out.

The Core Changelog lists its pages down to each version, not its thousands of entries. Those are in Changelog-<major>.json, with their type, issue, tags and version to filter by, and each links its page.

The docs homepage writes none: the llms.txt of docs.typo3.org is written by hand.
