# Registry (https://www.agentenvframework.com/docs/registry)

> The four stores that keep what you register and what your runs record

The registry is four stores, each local by default and swapped in `config.toml`.
[Core Concepts](https://www.agentenvframework.com/docs/core-concepts.md#the-registry) shows
which ones each workflow touches, and these pages cover one store each.

1. [Document Store](https://www.agentenvframework.com/docs/registry/document-store.md): versioned records and run history.
2. [Object Store](https://www.agentenvframework.com/docs/registry/object-store.md): the bytes those records point at.
3. [Image Store](https://www.agentenvframework.com/docs/registry/image-store.md): the container images envs and agents run.
4. [Secret Store](https://www.agentenvframework.com/docs/registry/secret-store.md): the values behind `secret:` references.
