 Catalogd is a Kubernetes extension that unpacks [file-based catalog (FBC)](https://olm.operatorframework.io/docs/reference/file-based-catalogs/#docs) content for on-cluster clients. Currently, catalogd unpacks FBC content that is packaged and distributed as container images. The catalogd road map includes plans for unpacking other content sources, such as Git repositories and OCI artifacts. For more information, see the catalogd [issues](https://github.com/operator-framework/catalogd/issues/) page. 
 
-Catalogd helps customers discover installable content by hosting catalog metadata for Kubernetes extensions, such as Operators and controllers. For more information on the Operator Lifecycle Manager (OLM) v1 suite of microservices, see the [documentation](https://github.com/operator-framework/operator-controller/docs/) for the Operator Controller.
