 ## Running with docker-compose
 
 The `docker-compose` provided configuration will prepare three containers.
-The first one called `skosmos-fuseki`, which uses the `stain/jena-fuseki`
-image for Jena, and starts a container with 2 GB of memory and `admin` as
-the user and password. The `docker-compose` service name of this container
