# Reference

URL: https://pagegraph.arya.sh/docs/reference

Reference pages for PageGraph CLI commands, package entries, check rules and configuration options, with the facts to look up while you work.

Reference pages state what exists and how it behaves. For task steps, see the [how-to guides](/docs/guides).

- [CLI commands](/docs/reference/cli): every `pagegraph` command and the stdout and stderr convention.
- [Package entries](/docs/reference/entries): what each entry exports, where it runs and what it needs.
- [Check rules](/docs/reference/check-rules): every structural and editorial rule, and what each checks.
- [Configuration](/docs/reference/configuration): plugin options and `pagegraph.config.ts` fields.
