## What Gets Synced

For each repo, the following files are collected:

| Source | Destination |
|--------|-------------|
| `README.md` | `index.md` |
| `CLAUDE.md` | `claude.md` |
| `CHANGELOG.md` | `changelog.md` |
| `docs/*.md` | `*.md` |

## Integration with core.help

The synced docs are used to build https://core.help:

1. Run `core docs sync --output ../core-php/docs/packages`
2. VitePress builds the combined documentation
3. Deploy to core.help
