 SciCat has extra features as part of its core as well as integrating with external services.
 
 SciCat features that extend the backend are:
-* Jobs - this mechanism posts to a message broker, which can then trigger down stream processes. To use this a RabbitMQ server enabled.
-* Elasticsearch - creates an elasticsearch service to provide full text search in the backend.
+* Jobs - this mechanism posts to a [message broker](./services/backend/services/v3/services/rabbitmq/), which can then trigger [down stream processes](./services/backend/services/v3/services/archivemock/). To use this a RabbitMQ server is enabled.

 Services that can be integrated with SciCat are:
-* LDAP - authentication and authorization from an LDAP server
-* OIDC - authentication and authorization using an OIDC provider
-* SearchAPI - for better free text search in the metadata based on the PANOSC [search-api](https://github.com/SciCatProject/panosc-search-api/)
-* LandingPage - a public interface for published datasets [landingpage](https://github.com/SciCatProject/LandingPageServer)
-* JupyterHub - Adds an instance of JupyterHub which demonstrates ingestion and extraction of metadata using [pyscicat](https://scicatproject.github.io/pyscicat/).

 1. follow the steps from the [basic section](#basic)
 2. eventually, include any service, in the service-specific folder which is specific to the service and not shared by other, more general services, e.g. [here](./services/backend/services/). This folder should also include different versions of the same service, e.g. v3 and v4 [here](./services/backend/services/)
