# Reference (source folder)

The reference docs render at https://product-on-purpose.github.io/pm-skills/reference/.

**This README is the GitHub directory landing page.** The full overview lives in [`index.md`](index.md), which is what renders on the docs site at `/reference/`. Edits to the rendered overview should land in `index.md`.

This folder holds authoritative reference material:

- Specs: `frontmatter-schema.yaml`, `pm-skill-anatomy.md`, `pm-skill-versioning.md`
- Catalogs: `commands.md`, `categories.md`
- Architecture and ecosystem: `project-structure.md`, `ecosystem.md`
- Skill family contracts: `skill-families/`

For the full table of files with purposes and "when to read it" notes, see [`index.md`](index.md).
