+description: Ingesting organizational data from Okta into Backstage
+---
+
+The Backstage catalog can be set up to ingest organizational data — users and
+groups — directly from Okta. The result is a hierarchy of
+[`User`](../../features/software-catalog/descriptor-format.md#kind-user) and
+[`Group`](../../features/software-catalog/descriptor-format.md#kind-group) kind
+entities that mirror your Okta organization.
+
+This integration is provided by the community-maintained
+[`@roadiehq/catalog-backend-module-okta`](https://github.com/RoadieHQ/roadie-backstage-plugins/tree/main/plugins/backend/catalog-backend-module-okta)
+plugin, owned and maintained by [Roadie](https://roadie.io/).
+
+## Installation and configuration
+
+For setup instructions, including authentication options (API token and OAuth
+2.0), user/group filtering, custom naming strategies, and entity transformers,
+see the
+[plugin documentation maintained by Roadie](https://github.com/RoadieHQ/roadie-backstage-plugins/tree/main/plugins/backend/catalog-backend-module-okta).
