# Catalog composition

The catalog documentation now lives in one place:

➡️ **[docs/catalog-guide.md](../../docs/catalog-guide.md)**

It covers composing a catalog, the built-in components, adding manifests for
the Agent handshake, the basic-catalog functions, why there is no
`catalog/all` aggregate, the paste-able "every built-in" recipe, custom
components, and the full catalog API reference.
