+
+Our GitLab registry keeps a copy of the container with the latest code, ready to be downloaded and used right away. With Docker installed, issue the following command in a terminal:
+
+```terminal
+$ docker pull registry.scicore.unibas.ch/schwede/ma-wilkins-import/converter:latest
+```

+
+```terminal
+$ docker pull registry.scicore.unibas.ch/schwede/ma-wilkins-import/converter:latest
