 ## Plugin
 
-- The plugin is disabled by default. See the TypeScript type for the [the available plugin configuration options](https://github.com/elastic/kibana/blob/master/x-pack/plugins/ingest_manager/common/types/index.ts#L9-L27)
-- Setting `xpack.ingestManager.enabled=true` enables the plugin including the EPM and Fleet features. It also adds the `PACKAGE_CONFIG_API_ROUTES` and `AGENT_CONFIG_API_ROUTES` values in [`common/constants/routes.ts`](./common/constants/routes.ts)
